Problem 1: The coefficient of restitution for steel colliding with steel is 0.95. If steel is dropped from a height ho above steel plate, to what height will the ball rebound.
Problem 2: in an elastic head on collision with a stationary target particle, a moving particle recoils of its incident speed. What is the ration of the particles masses (m/M)
2. mv= mv + MV
The Attempt at a Solution
1. -e= (v2-v1)/(v2o-v1o)
From there I honestly have no clue what to do.
2. mv = m(-1/3V) +MV
4/3mv = MV
The book answer is 1/2, and I'm working with thirds? Should I be using a KE equation?
Any help is appreciated.
