## Question:

The three balls each have weight W and have a coefficient of restitution e. If ball A is released from rest and strikes ball B and then ball B strikes ball C, determine the velocity of each ball after the second collision has occurred. The balls slide without friction. Given: W = 0.5 lb , r = 3 ft ,e = 0.85 , g = ${ 32.2ft/s }^{ 2 }$
