The time of flight is obtained as 25.9 seconds

The time of flight is the time taken to move the object that have been projected along the parabolic path. In this case, we have a cannonball that have been fired  from level ground with a velocity of 240.0 m/s at an angle of 32 degrees.

We know that from the question

T = 2usinθ/g

T = time of flight

u = initial velocity

θ = angle of projection

g = acceleration

T = 2 * 240.0 m/s * sin 32 degrees/9.8 m/s^2

T = 25.9 seconds

The main difference between Kinetic energy and Potential energy is that kinetic energy refers to movement while potential energy refers to storage.

Kinetic energy is a type of energy in motion or energy in movement such as a turbine (mechanical energy), while Potential energy refers to the energy that is stored to be used when required (e.g. chemical bonds of foods).

Therefore, with this data, we can see that  Kinetic energy is used as movement, while Potential energy is stored to be used in the future.

The velocity after 2 seconds is 26 m/s. It takes 11.50 seconds to reach a velocity of 40m/s.

Given the equation s(t) = 6t + 5t²

Let's find the velocity after 2 seconds.

(a) Velocity = (ds)/(dt)

Differentiating s(t) with respect to t, we get; ds(t) / dt = 6 + 10t

At t = 2,ds(t) / dt = 6 + 10t = 6 + 10(2) = 26m/s

Therefore, the velocity after 2 seconds is 26 m/s.

(b) We are to find how long it takes for the velocity to reach 40m/s. We know that the initial velocity of the ball, u = 6m/s. Acceleration = gsinθ = 9.81 x sin (angle of inclination) = 9.81 x 0.3 = 2.943 m/s²From the first equation of motion, v = u + at

We know v = 40m/s, u = 6m/s, a = 2.943m/s² and t is what we are to find, hence the equation becomes;40 = 6 + 2.943(t)t = (40 - 6) / 2.943t = 11.50s

Therefore, it takes 11.50 seconds to reach a velocity of 40m/s.

"170 Degrees" is a temperature measurement unit commonly used in the Fahrenheit scale. If you are trying to convert "170 Degrees" from Fahrenheit to Celsius, it is important to understand how the two scales relate to each other.

The Fahrenheit scale is based on 32° being the temperature at which water freezes and 212° being the temperature at which water boils. In contrast, the Celsius scale has 0° as the temperature at which water freezes and 100° as the temperature at which water boils.

To convert "170 Degrees" from Fahrenheit to Celsius, you can use the formula:

C = (F - 32) * 5/9, where F is the temperature in Fahrenheit and C is the temperature in Celsius.

Plugging in "170 Degrees" for F, we get:

C = (170 - 32) * 5/9 = 76.67 * 5/9 = 76.67 * 0.5556 = 42.78°C.

So "170 Degrees" Fahrenheit is equivalent to 42.78°C in the Celsius scale.

If the intensity of the loud machine were reduced by a factor of 5, the new intensity level would be 90 dB.

This can be calculated using the formula for decibel levels, which states that the difference in decibel levels is equal to 10 times the logarithm of the ratio of the two intensities. So, if the original intensity level was 110 dB, reducing it by a factor of 5 would result in a new intensity level that is 10 times lower, which is equivalent to a reduction of 20 dB. Therefore, the new intensity level would be 90 dB (110 dB - 20 dB = 90 dB).
If a loud machine produces sounds with an intensity level of 110 dB and the intensity is reduced by a factor of 5, the new intensity level can be calculated using the decibel formula: dB = 10 * log10(I/I₀), where I is the intensity and I₀ is the reference intensity. First, find the original intensity (I) using the inverse formula: I = I₀ * 10^(dB/10). Then, divide the original intensity by 5 and use the decibel formula again to find the new intensity level. The new intensity level will be lower than the initial 110 dB due to the reduced intensity of the sound.

The time it takes for the drop ride in Acrophobia at Six Flags Georgia is  3.53 seconds, ignoring air resistance.

We apply the principles of free fall motion.

note that Free-falling objects do not encounter air resistance and that  all free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s

t = √(2h/g)

t = time of free fall

h = height of the drop

g = acceleration due to gravity=  9.8 m/s² on Earth

Height of the drop (h) = 61.0 m

Acceleration due to gravity (g) = 9.8 m/s²

t = √(2 * 61.0 / 9.8)

According to Wien's law, the color of the sun should be a bright white or slightly bluish-white. This is because Wien's law states that the peak wavelength of the sun's radiation is in the ultraviolet region, which corresponds to a color on the blue end of the visible spectrum.

However, since the sun emits radiation across a broad range of wavelengths, it appears as a bright white ball in the sky to the human eye.

Based on Wien's Law, the Sun's color is primarily white. Wien's Law helps determine the peak wavelength of radiation emitted by a black body, such as the Sun, based on its temperature. The Sun's surface temperature is around 5,500°C (9,932°F), which corresponds to a peak wavelength in the visible light spectrum, causing it to appear white to the human eye.

It would take 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

To calculate the time required to crumple the barrier and safely slow down the person, we can use the concept of impulse.

The impulse, denoted by J, is defined as the product of force and time, and it represents the change in momentum of an object. In this case, the impulse required to safely slow down the person can be calculated using the maximum force and the person's initial momentum.

The momentum of a person is given by the product of their mass and velocity:

Momentum = mass × velocity

Given that the person's mass is 68 kg and their velocity is 27 m/s, the initial momentum is:

Initial momentum = 68 kg × 27 m/s

To safely slow down the person, the impulse provided by the barrier should be equal to the change in momentum.

Therefore, we have:

Impulse provided by barrier = Final momentum - Initial momentum

Since the person is brought to rest, the final momentum is zero. Thus, we have:

Impulse provided by barrier = -Initial momentum

Now we can express the impulse in terms of force and time:

Impulse provided by barrier = Force × Time

Plugging in the known values, we can solve for time:

-Initial momentum = Force × Time

68 kg × 27 m/s = 1180 N × Time

Simplifying the equation, we find:

Time = (68 kg × 27 m/s) / 1180 N

Evaluating the expression:

Time = 1836 kg·m/s / 1180 N

Finally, converting kg·m/s to seconds, we get:

Time ≈ 1.5559 seconds

Therefore, it would take approximately 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

The velocity that the car will have is 220 m/s.The work done on a body is equal to the change in its kinetic energy.

To determine the velocity that a 1000 kg car will have when supplied with the energy supplied by the battery, we can calculate the work done and equate it to the change in kinetic energy.

Work done = Change in kinetic energy `W=ΔKE`

Energy supplied by the battery = 1/2mv²(2.0×10⁵ C)(12 V) = (1/2) × (1000 kg) × v²v² = (2 × 10⁵ C × 12 V × 2) / 1000 kg

v² = 4.8 × 10⁴ m²/s²v = √(4.8 × 10⁴) m/sv = 220 m/s

Therefore, the velocity that the car will have is 220 m/s.
