A 1 kg object moving at 5 m/s collides with a wall and comes to rest. What average force acts if the collision lasts 0.5 seconds?
To calculate the average force, we can use the impulse-momentum theorem:
Impulse is also equal to the change in momentum:
Given:
(mass of the object)
Initial velocity
Final velocity (since the object comes to rest)
(time duration of the collision)
The change in velocity is:
