Problem 4 (25 points) - show detailed steps Two identical balls come into a collision with a coefficient of restitution e=0.8. Before the impact, VA = 7 m's and vg = 3 m/s. Their directions are as shown. Determine the magnitude of velocity of each ball after the impact. Include the following steps in your VB solution: a) Define a coordinate system appropriately (3 pts) b) Calculate the two components of each velocity before the impact. (6 pts) c) Apply the right principle(s)/equation(s) to determine the component velocities of each ball after impact. (12 pts) VA d) Determine the magnitude of the velocity of each ball after the impact. (4 pts) 2007
