A ball of 0.3 kg is traveling toward a wall in the +x direction with a speed of 15m/s. It strikes the wall and bounces directly back with the speed of 12m/s. Determine its change in momentum?
In the question above the ball is in contact having the wall for 0.03s
i) Determine the impulse delivered to the ball?
ii) Determine the average force applied on the ball by the wall? (Comprise the direction!)
