A steel ball of mass Melastically rebounds off of a steel wall. The ball is originally a distance d from the wall at its path will meet the wall after travelling a distance D while moving at a speed V. During the collision the ball has an effective spring constant K. What is the maximum force that the ball feels during the collision? M Questions to ask yourself: D (a) How long is the interaction? (b) What is the average force on the ball? (c) What would happen if there were friction along the wall? What would the final velocity be? How would the speed change? The direction of travel?
