Automobile manufacturers, such as Nissan and Toyota, incorporate safety features into their vehicles. Crumple zones in the engine compartment and air bags are two examples of safety technology designed to protect driver and passengers involved in a collision. How do these design features impact the formula above and the force of impact? They decrease the force of impact by providing a cushion during the impact. Smaller force = lower momentum. They decrease the force of impact by extending the time it takes to stop the driver and passenger. Longer time = less force. It takes a longer time for the velocity of the vehicle to decrease, therefore the force is less. Decrease in velocity = less force. When a car rebounds it undergoes a greater change in velocity and the force is decreased. Lower force = greater change in velocity.​

We have that  the final velocity of a ball thrown downward at 10 m/s after 2 seconds is

V=29.6m/s

From the question we are told

What is the final velocity of a ball thrown downward at 10 m/s after 2 seconds?

Where

Generally the Newton's equation for Motion   is mathematically given as

[tex]V=U+at\\\\V=U+gt\\\\V=10+9.8*2\\\\V=29.6m/s[/tex]

Therefore

the final velocity of a ball thrown downward at 10 m/s after 2 seconds is

V=29.6m/s

Explanation:

because if a tennis ball hit a tennis racket still it would not go anywhere. with the tennis ball hitting the moving racket it will go further

One that is in motion because both the ball and the racquet will contribute momentum.

Thus, option (c) is correct.

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

When the tennis ball hits a tennis racquet in motion, both the ball and the racquet will exert forces on each other in opposite directions.

This interaction will result in a transfer of momentum from the racquet to the ball and vice versa, potentially giving the ball a greater momentum and therefore potentially causing it to go farther.

Thus, option (c) is correct.

Answer:

Displacement=10 meters

Explanation:

The displacement is the direct path from the first contact with the ball and the last spot it was seen in. The ball was kicked north 8 meters, meaning it was kicked vertically upward, and then it was kicked east 6 meters, or to the right. If we were to draw the displacement we would see that this is a right triangle. That means we can use the Pythagorean Theorem:

[tex]a^2+b^2=c^2\\8^2+6^2=c^2\\64+36=c^2\\c^2=100\\\sqrt{c} =\sqrt{100} \\c=10[/tex]

Boom.

The displacement is 10 m toward the northeast. The first option is correct.

The displacement is a vector quantity having both magnitude and direction. It is equal to the path length between the initial and final positions.

Given:

North displacement, y=8 m

East displacement, x= 6 m

The net displacement is calculated using Pythagoras' theorem as the displacements are perpendicular to each other.

The displacement is given by:

d=√(x²+y²)

d=√(8²+6²)

d=10 m

So, the displacement is 10 m.

Therefore, the displacement is 10 m toward the northeast. The first option is correct.

This cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.

Given the following data:

To find the net force acting on the cart:

A net force can be defined as the vector sum of all the forces that are acting on a physical object or body.

This ultimately implies that, a net force is a single (one) force that substitutes the effect of all the forces acting on a physical object or body.

Mathematically, net force is given by the following:

[tex]Net \;force = F_1 + F_2 + F_3 + F_4 + .....F_n[/tex]

Where:

[tex]Net\; force = 60 + 30 + (-90)\\\\Net\; force = 90 - 90[/tex]

Net force = 0 Newton

Based on Newton's First Law of Motion, this cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.

The scaled diameters of the missing planets are listed below:

Mercury                      1.4 cm

Saturn                      33.1 cm

Uranus                     14.0 cm

Neptune                  13.6 cm

In this question we must use conversion factor to calculate the scaled diameters by means of the following direct relationship:

d = k · D     (1)

Where:

The conversion factor is found by using the real and scaled diameter of the Earth:

k = 3.5 cm/12,756 km

k = 7/25512 cm/km
