consider that a ball with a mass of 0.5kg is thrown at 20m/s and remains midair for 2 seconds before hitting a wall. in order to find the force measured in newtons the first step is working to find the acceleration. What is the acceleration of the ball?

Answer 1

To find the acceleration of the ball, we can use the equation:

acceleration = (final velocity - initial velocity) / time

Given:
Initial velocity (u) = 20 m/s
Final velocity (v) = 0 m/s (since the ball stops after hitting the wall)
Time (t) = 2 seconds

Using the equation:

acceleration = (0 - 20) / 2
= -20 / 2
= -10 m/s²

Therefore, the acceleration of the ball is -10 m/s² (negative sign indicates that it is decelerating).

Answer 2

This is just crazy.
The ball did not stop during the 2 second flight.
We do not know how long it took to stop AFTER it hit the wall.
Therefore we can not calculate the change of momentum in whatever time .

Answer 3

I apologize for the confusion. You are correct, the given information does not allow us to directly calculate the acceleration or the force experienced by the ball while it is midair. In order to determine the force, we would need additional information such as the time it takes for the ball to come to a stop after hitting the wall or the distance over which it comes to a stop. Without this information, we cannot accurately determine the force experienced by the ball.
