What is the total momentum of the system above? _kg.m/s
After they collide what will be the total momentum ? _ kg.m/s

To determine the x- and y-components of each vector, we can use trigonometry.

For vector A:

x-component = 230 cos(15°) ≈ 222.85

y-component = 230 sin(15°) ≈ 59.27

For vector B:

x-component = 120 cos(237°) ≈ -107.75

y-component = 120 sin(237°) ≈ -75.94

For vector C:

x-component = 212 cos(188°) ≈ 112.84

y-component = 212 sin(188°) ≈ -163.63

To determine the direction and magnitude of the resultant vector, we can add up the x- and y-components of each vector.

x-component = 222.85 - 107.75 + 112.84 ≈ 227.94

y-component = 59.27 - 75.94 - 163.63 ≈ -180.3

The magnitude of the resultant vector is given by the Pythagorean theorem:

resultant magnitude = sqrt((227.94)^2 + (-180.3)^2) ≈ 292.9

The direction of the resultant vector is given by the arctangent of the y-component over the x-component:

resultant direction = atan(-180.3/227.94) ≈ -38.5°

Therefore, the answers to the questions are:

To move left or right (x-direction only): A) 53.1 Left

To move up or down (y-direction only): C) 69.1 Down

To move away from starting point and at what angle: D) 88.3 < 233.

An angle is a geometric figure that is formed by two rays or line segments that share a common endpoint, known as the vertex of the angle. The rays or line segments are referred to as the sides or legs of the angle. The measure of an angle is typically given in degrees, which is a unit of measurement for angles. One complete revolution around a circle corresponds to 360 degrees, while a half revolution corresponds to 180 degrees.

The full three-dimensional strain tensor at the point

\(p = e_1 + 2e_2 + 10e_3\: is\: :\\epsilon =\left[\begin{array}{ccc}0.05x_2&0.05x_1&0\\0.05&0&0\\0&0&0\end{array}\right]\)

To calculate the full three-dimensional strain at the point \(p = e_1 + 2e_2 + 10e_3\), we need to find the components of the strain tensor \(\epsilon_m_n\).

The strain tensor εₘₙ can be calculated using the formula:

εₘₙ = (0.5) * (∂uₘ/∂xₙ + ∂uₙ/∂xₘ)

Given the displacement field u(x, t) with components:

u₁ = 0.1x₁x₂

u₂ = 0.1x₂ + 5

u₃ = 500

We can calculate the components of the strain tensor as follows:

\(\epsilon_1_1 = (1/2) * (\delta u_1/\delta x_1 + \delta u_1/\delta x_1)\\= (1/2) * (0.1x_2 + 0)\\= 0.05x_2\)

\(\epsilon_1_2 = (1/2) * (\delta u_1/\delta x_2 + \delta u_2/\delta x_1)\\= 0.05x_1\)

\(\epsilon _1_3 = (1/2) * (\delta u_1/∂x_3 + \delta u_3/\delta x_1)\\= (1/2) * (0 + 0)\\= 0\)

\(\epsilon_2_1 = (1/2) * (\delta u_2/\delta x_1 + \delta u_1/\delta x_2)\\= (1/2) * (0 + 0.1)\\= 0.05\)

ε₂₃ = (1/2) * (∂u₂/∂x₃ + ∂u₃/∂x₂)

= (1/2) * (0 + 0)

= 0

ε₃₁ = (1/2) * (∂u₃/∂x₁ + ∂u₁/∂x₃)

= (1/2) * (0 + 0)

= 0

ε₃₂ = (1/2) * (∂u₃/∂x₂ + ∂u₂/∂x₃)

= (1/2) * (0 + 0)

= 0

ε₃₃ = (1/2) * (∂u₃/∂x₃ + ∂u₃/∂x₃)

= (1/2) * (0 + 0)

= 0

Therefore, the full three-dimensional strain tensor at the point

The distance traveled before the car comes to a stop is approximately 75.7 ft (rounded to one decimal place).

Explanation:

Deceleration is the opposite of acceleration, and it refers to the rate at which an object slows down or decreases its velocity. Mathematically, deceleration is the negative acceleration. When an object is decelerating, it is experiencing a net force in the opposite direction of its velocity, causing it to slow down.

a car, traveling, and constant deceleration. To find the distance traveled before the car comes to a stop, we can use the following steps:

Step1. Convert the initial velocity (50 mi/h) to ft/s:
(50 mi/h) * (5280 ft/mi) * (1 h/3600 s) = 73.3 ft/s

Step2. Use the formula vf^2 = vi^2 + 2ad to find the distance (d), where vf is the final velocity (0 ft/s), vi is the initial velocity (73.3 ft/s), and a is the constant deceleration (-28 ft/s^2):
0 = (73.3 ft/s)^2 + 2(-28 ft/s^2)(d)

Step3. Solve for the distance (d):
d = (73.3 ft/s)^2 / (2 * 28 ft/s^2) = 75.7 ft

So, the distance traveled before the car comes to a stop is approximately 75.7 ft (rounded to one decimal place).

Elephant and the eath because Fg is determined by Mass of an object.. So elephant has greater mass therefore, it's Fg is higher

According the universal  law of gravitation, the gravitational force is directly proportional to the mass of an object.  An elephant weighs so much than a man and thus it will experience larger gravitational force from earth.

Gravitational force is a resistive force by which an object attracts other objects towards its centre of mass. The force exerted by the object depends on the mass and the force experienced by the other object depends on its mass and distance between the two objects.

According to universal law of gravitation, the gravitational force is directly proportional to the mass of the object and distance from the ground. The expression for the law is written as:

\(\rm g = G \frac{M_{1} M_{2}}{r^{2}}\)

Where, G is the universal gravitational constant and M1 and M2 be the masses of two objects which and r be the distance between them. As per this relation gravity decreases with increase in distance and increase with an increase in mass.

A 100 kg shot-putter pushes on a 4 kg shot with a force of 500 n forward and a force of 866 n upward,  the resultant force acting on the shot is: 1000.42 N

Given,
mass of the shot-putter (m) = 100 kg
mass of the shot (M) = 4 kg
force along the x-axis (F_x) = 500 N
force along the y-axis (F_y) = 866 N

The force acting on the shot is the resultant force of F_x and F_y.
The resultant force acting on the shot is given by the equation
R = √(F_x² + F_y²)

R = √(500² + 866²)
R = √(250000 + 750856)
R = √1000856
R = 1000.42 N

Therefore, the resultant force acting on the shot is 1000.42 N. The force acting on the shot is the resultant of F_x and F_y. The shot is moved by this force.The given problem can be solved using Newton's laws of motion. To understand the resultant force acting on the shot, we need to understand what the hot-putter does.

He applies force to the shot along both the x and y axes to move the shot forward. Thus, the resultant force of both the forces is the actual force that the shot experiences. It is worth noting that this resultant force is different from the forces applied by the hot-putter, but it causes the shot to move.

The initial velocity of the object is approximately 6.67 m/s.

To determine the initial velocity of the object, we can use the formula for average velocity:

Average velocity (\(V_{avg}\)) = (final velocity - initial velocity) / displacement

We have two data points:

When the object has traveled 50 m, its velocity is 7 m/s.

When the object has traveled 150 m, its velocity is 10 m/s.

Let's denote the initial velocity as \(V_i\).

Using the first data point:

\(V_{avg\) = (7 m/s - \(V_i\)) / 50 m

Using the second data point:

\(V_{avg\) = (10 m/s - \(V_i\)) / 150 m

Since the average velocity should be the same in both cases, we can equate the two expressions:

(7 m/s - \(V_i\)) / 50 m = (10 m/s - \(V_i\)) / 150 m

Now, we can solve this equation to find the initial velocity.

Cross-multiplying:

150 m * (7 m/s - \(V_i\)) = 50 m * (10 m/s - \(V_i\))

Expanding the equation:

1050 \(m^2\)/s - 150 m * \(V_i\) = 500 \(m^2\)/s - 50 m * \(V_i\)

Rearranging terms:

1000 \(m^2\)/s - 150 m *\(V_i\) = 0

Now, solving for \(V_i\):

150 m * \(V_i\)= 1000 \(m^2\)/s

\(V_i\) = (1000 \(m^2\)/s) / 150 m

\(V_i\)  ≈ 6.67 m/s

The initial velocity of the object is approximately 4.85 m/s.

Let's denote the initial velocity of the object as v₀. We are given that when the object has traveled 50 m, its velocity is 7 m/s, and when it has traveled 150 m, its velocity is 10 m/s.

Using the equations of motion, we can relate the distance, velocity, and initial velocity. The equation we can use is:

v² = v₀² + 2aΔx

where v is the final velocity, v₀ is the initial velocity, a is the acceleration, and Δx is the distance traveled.

From the first set of data, when the object has traveled 50 m and its velocity is 7 m/s, we can substitute these values into the equation:

(7 m/s)² = v₀² + 2a(50 m)

Simplifying this equation gives us:

49 m²/s² = v₀² + 100a

Similarly, from the second set of data, when the object has traveled 150 m and its velocity is 10 m/s, we can substitute these values into the equation:

(10 m/s)² = v₀² + 2a(150 m)

Simplifying this equation gives us:

100 m²/s² = v₀² + 300a

Now we have two equations:

49 m²/s² = v₀² + 100a   (Equation 1)

100 m²/s² = v₀² + 300a   (Equation 2)

To solve for v₀, we can subtract Equation 1 from Equation 2:

100 m²/s² - 49 m²/s² = (v₀² + 300a) - (v₀² + 100a)

51 m²/s² = 200a

Solving for a gives us:

a = (51 m²/s²) / 200 ≈ 0.255 m/s²

Now we can substitute this value of acceleration back into Equation 1 to solve for v₀:

49 m²/s² = v₀² + 100(0.255 m/s²)

49 m²/s² = v₀² + 25.5 m²/s²

Subtracting 25.5 m²/s² from both sides gives us:

23.5 m²/s² = v₀²

Taking the square root of both sides gives us:

v₀ = √(23.5 m²/s²)

v₀ ≈ 4.85 m/s

Therefore, the initial velocity of the object is approximately 4.85 m/s.

In this scenario, the temperature of the air increases as it is compressed, making option b (warmer) the correct answer.

When a volume of air is compressed with no heat entering or leaving the system, the process is known as adiabatic compression. This phenomenon occurs because the work done on the air to compress it increases its internal energy. According to the First Law of Thermodynamics, the increase in internal energy results in a rise in temperature.

Adiabatic compression is common in natural processes, such as when air rises in the atmosphere and cools down or when it descends and warms up. It is also a critical concept in various industrial applications, including air compressors, refrigeration systems, and gas turbine engines.

Explanation:

The kinematic formula for distance, given a uniform acceleration a and an initial velocity v₀, is

\(d=v_0t+\frac{1}{2}at^2\)

This car is starting from rest, so v₀ = 0 m/s. Additionally, we have a = 9.2/9.7 m/s² and t = 9.7 s. Plugging these values into our equation:

\(d=0t+\frac{1}{2}\left(\frac{9.2}{9.7}\right)(9.7)^2\\d=\frac{1}{2}(9.2)(9.7)\\d=4.6(9.7)\\d=44.62\)

So, the car has travelled 44.62 m in 9.7 seconds - we want to know how many of the tire's circumferences fit into that distance, so we'll first have to calculate that circumference. The formula for the circumference of a circle given its diameter is \(c=\pi{d}\), which in this case is 47.8π cm, or, using π ≈ 3.14, 47.8(3.14) = 150.092 cm.

Before we divide the distance travelled by the circumference, we need to make sure we're using the same units. 1 m = 100 cm, so 105.092 cm ≈ 1.5 m. Dividing 44.62 m by this value, we find the number of revs is
