Asked by David
A ball bounces to 34 percent of its original height.
*1) What fraction of its mechanical energy is lost each time it bounces?
*2) What is the coefficient of restitution of the ball-floor system?
- I was able to solve part one and get an answer of .66, but part two I don't know how to approach without a given mass, velocity etc.

mghbounce/origianal mgh=.34
so the energy lost is .66 or 2/3 lost
coeffrestitution=.34
so the energy lost is .66 or 2/3 lost
coeffrestitution=.34
