a. calculate the height (in m) of a cliff if it takes 2.14 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.07 m/s. (enter a number.)
b. How long would it take to reach the ground if it is thrown straight down with the same speed?

Answers

Answer 1

a) Height of the cliff will be -3.7031 m

b) It would take 0 seconds to reach the ground if it is thrown straight down with the same speed

a. The height of the cliff can be calculated using the equation of motion for vertical motion under constant acceleration. The equation is given by:

h = (v_i * t) - (0.5 * g * t^2)

where:

h is the height of the cliff,

v_i is the initial velocity (8.07 m/s in this case),

t is the time taken for the rock to hit the ground (2.14 s),

g is the acceleration due to gravity (approximately 9.8 m/s^2).

Let's substitute the values into the equation to calculate the height:

h = (8.07 m/s * 2.14 s) - (0.5 * 9.8 m/s^2 * (2.14 s)^2)

h = 17.2998 m - 21.0029 m

h = -3.7031 m

Since the height cannot be negative in this context, we can conclude that the calculated value is not valid. This indicates an error in the problem statement or calculations.

b. To determine the time it takes for the rock to reach the ground when thrown straight down with the same speed (8.07 m/s), we can use the equation of motion:

h = (v_i * t) + (0.5 * g * t^2)

We want to find the time when h = 0 (reaches the ground). Rearranging the equation gives us:

0 = (8.07 m/s * t) + (0.5 * 9.8 m/s^2 * t^2)

Rearranging further, we obtain a quadratic equation:

4.9 t^2 + 8.07 t = 0

To solve this quadratic equation, we factor out t:

t(4.9t + 8.07) = 0

This equation yields two possible solutions: t = 0 and t = -8.07/4.9. Since time cannot be negative in this scenario, we discard the negative solution.

Therefore, the time it would take for the rock to reach the ground when thrown straight down with the same speed is t = 0.

Based on the calculations, we encountered an inconsistency in part a, where the calculated height turned out to be negative. This suggests an error in either the initial velocity, time, or other factors mentioned in the problem statement. In part b, we found that the time it takes to reach the ground when thrown straight down with the same speed is t = 0. This indicates that the rock would hit the ground instantaneously when thrown straight down. However, it is important to review the initial problem statement and values provided to ensure accurate calculations and valid results.

The question that how many hours a day dolphins sleep requires the collection of data to answer it. Hence, option B is correct.

What are dolphins?

Dolphins are small-toothed cetaceans that are distinguished by their always open, curving mouths. Every ocean contains one of the 36 dolphin species. The majority of dolphins are marine mammals that inhabit the sea or coastal environments with brackish water. However, there are a few species that live in freshwater streams and rivers, including the South Asian river dolphin and the Amazon River dolphin, or boto.

The orca, the biggest dolphin, can reach lengths of more than 30 feet. The Maui dolphin, which is the smallest, is only five feet long.

Dolphins mostly consume fish and squid, which they can locate via echolocation, an inbuilt sonar system that reflects sound waves off prey to disclose details about its location, size, and shape. Up to a thousand clicking sounds can be heard every second from an echo locating bottlenose dolphin.

if 134,102 j of thermal energy was generated going from point 1 to point 4, how fast would a 702 kg roller coaster be going at point 4? state the appropriate mks units with your answer.

Answers

The speed of roller coaster would be 14.8 m/s

To calculate the speed of the roller coaster at point 4, we can use the conservation of energy principle, which states that the initial energy of the system (potential energy + kinetic energy) is equal to the final energy of the system.

Assuming that point 1 is the highest point of the roller coaster and that there is no friction or other energy losses, we can use the following equation:

mgh = (1/2)mv^2

where,

m is the mass of the roller coaster,

g is the acceleration due to gravity,

h is the height of point 1 above point 4,

v is the speed of the roller coaster at point 4.

Solving for v, we get:

v = sqrt(2gh)

where,

h is the vertical distance between point 1 and point 4.

Now, we need to find the value of h. The thermal energy generated in going from point 1 to point 4 is not directly related to the height difference, but we can assume that all of the potential energy at point 1 is converted to thermal energy at point 4, and that the roller coaster loses no energy due to friction or other factors.

Therefore, we can use the formula for potential energy:

mgh = 134102 J

Solving for h, we get:

h = 134102 J / (mg)

Substituting the given values, we get:

h = 134102 J / (702 kg x 9.81 m/s^2) = 19.1 m

Finally, substituting the value of h into the equation for speed, we get:

v = sqrt(2 x 9.81 m/s^2 x 19.1 m) = 14.8 m/s

Therefore, the roller coaster would be going 14.8 m/s at point 4.

Your 1000-m-long starship has warning lights at each end that, to you, flash simultaneously every minute. You are moving directly away from the planet Zerkon at 0.70c.
To a Zerkonian, do the lights flash simultaneously? If not, which flashes first-the light at the front of your ship or the trailing one?
Answer Choices:
A. The lights flash simultaneously.
B. The front light flashes first.
C. The trailing light flashes first.
D. Not enough information given to answer the question.

Answers

To a Zerkonian observer, the lights on your starship do not flash simultaneously. The trailing light flashes first.

This is due to the phenomenon of time dilation, predicted by Einstein's theory of relativity. As you, the observer on the starship, are moving away from the planet Zerkon at a high velocity of 0.70c (70% of the speed of light), time appears to be passing slower for you relative to the stationary frame of reference on Zerkon. As a result, the time interval between the flashes of the warning lights, which is one minute in your frame of reference, will be dilated or stretched from the perspective of the Zerkonian observer. The light at the front of your starship, which is moving away from Zerkon, takes longer to reach the observer compared to the light at the trailing end. Therefore, the trailing light will be observed to flash first by the Zerkonian observer. Hence, the correct answer is C. The trailing light flashes first.

Answers

Each solution tested has its advantages and disadvantages. The most effective solution depends on the situation and the amount of oil that needs to be removed from the water.

The three solutions tested to remove oil from water are scooping the oil with a spoon, absorbing the oil with a paper towel, and using soap to break up the oil. Each solution has its advantages and disadvantages. Scooping the oil with a spoon is an effective solution to remove a significant amount of oil quickly. However, it is not a practical solution for removing a large amount of oil. The disadvantage is that it spreads the oil around the surface of the water and leaves some oil in the water. Absorbing the oil with a paper towel can effectively remove a lot of oil. The advantage is that it removes some oil from the water, leaving it relatively clean. However, it also picks up a lot of water and can't get all of the oil. Using soap to break up the oil is a good solution that removes all of the oil from the water. The advantage is that it removes all of the oil from the water, leaving it clean. However, the disadvantage is that it disperses the oil on the surface of the water, making it harder to remove from the sides of the bowl. In conclusion, each solution tested has its advantages and disadvantages. The most effective solution depends on the situation and the amount of oil that needs to be removed from the water.

Answers

At the instant when the current in the inductor is increasing at a rate of 50.0A/s, we can use the concept of inductor behavior to find the current through R1.

Given that the switch SS is closed, the inductor will behave as a short circuit. This means that no current will flow through R1, and the current i1 through R1 will be zero.

When the switch SS is closed, the inductor behaves as a short circuit, allowing the current to flow through the path of least resistance. In this case, since the current in the inductor is increasing, it means that there is a changing magnetic field within the inductor, which induces a voltage across it. This induced voltage causes the inductor to act like a short circuit, diverting all the current away from R1. Therefore, at the instant when the current in the inductor is increasing at a rate of 50.0A/s, the current i1 through R1 will be zero.

Explanation:

The momentum of an object can be calculated using the equation:

$\large\boxed{p=mv}$

where:

p is momentum (measured in kilogram meters per second).m is mass (measured in kilograms).v is the velocity (measured in meters per second).

$\hrulefill$

Question 1

For this question we need to find the momentum of a bowling ball whose mass is 4.0 kg is rolling at a rate of 2.5 m/s.

Given values:

m = 4.0 kgv = 2.5 m/s

Substitute the given values into the momentum formula and solve for p:

$p=4.0\;\text{kg} \cdot 2.5\;\text{m/s}$

$p=10\;\text{kg m/s}$

Therefore, the momentum of the bowling ball is 10 kg-m/s.

$\hrulefill$

Question 2

For this question we need to find the mass of a skateboard rolling at a velocity of 3.0 m/s with a momentum of 6.0 kg-m/s.

Given values:

p = 6.0 kg-m/sv = 3.0 m/s

As we want to find mass, rearrange the momentum formula to isolate m:

$\large\boxed{m=\dfrac{p}{v}}$

Substitute the given values into the formula and solve for m:

$m=\dfrac{6.0\; \text{kg m/s}}{3.0\; \text{m/s}}$

$m=2\;\text{kg}$

Therefore, the mass of the skateboard is 2 kg.

$\hrulefill$

Question 3

For this question we need to find the velocity of a baseball with a mass of 0.5 kg and a momentum of 10 kg-m/s.

Given values:

p = 10 kg-m/sm = 0.5 kg

As we want to find velocity, rearrange the momentum formula to isolate v:

$\large\boxed{v=\dfrac{p}{m}}$

Substitute the given values into the formula and solve for v:

$v=\dfrac{10\; \text{kg m/s}}{0.5\; \text{kg}}$

$v=20\;\text{m/s}$

Therefore, the velocity of the baseball is 20 m/s.

When a student conducts an activity using a concave mirror with a focal length of 10 cm and places an object 15 cm away from the mirror, the image is likely to be formed behind the mirror. The distance of the image from the mirror is calculated using the mirror equation, which states that 1/f = 1/u + 1/v, where f is the focal length, u is the distance of the object from the mirror, and v is the distance of the image from the mirror. Substituting the values given in the question, we get 1/10 = 1/15 + 1/v. Solving this equation gives us v = -30 cm. The negative sign indicates that the image is formed behind the mirror, which is expected since the mirror is concave. The magnification of the image can be calculated using the formula m = -v/u, which gives us m = -30/15 = -2. This means that the image is inverted and its size is twice that of the object.
