Ball 1, with a mass of 159 g and traveling at 11.0 m/s ,collides head on with ball 2, which has a mass of 324 g and isinitially at rest. Assume that ball 1 is traveling to the rightbefore the collision and that the collision is one dimensional.
What is the final velocity of ball 1 if the collision isperfectly elastic?
Answer: -3.76 m/s
What is the final velocity of ball 2 if the collision isperfectly elastic?
Answer: 7.24 m/s
What are the final velocities of the combination if the ballsstick together?
Answer: 3.62
How much KE was lost when the balls stuck together?
