A ball dropped onto a floor from a height of 5m rises to a height of 2m after 3 bounces.What is the coefficient of restitution.? i know that e=(velocity of ball after 1st impact )/(velocity with which the ball strikes the floor).But will the no. of bounces effect the value of coefficient of restitution??
Answered by jaykim
the velocity with which it hit the ground vo=sqrt(2*10*5)=10m/s hn=e^nvo^2/2g 2=e^3(100)/2(10) e^3=0.4 e=0.632

the coefficient of restitution that is present on each bounce would be equal. let the second bounce be the new drop height.
