Expert Answer
Coefficient of restitution e of collision is ratio of relative velocity u after impact to the relative velocity v before impact .
e = v / u
if the ball is dropped from height H = 10 m , velocity u when the ball just hits the ground ,
or just before impact is given as
After impact , if the ball is raised to a height h = 2.5 m , velocity v after impact is given as
Then coefficient of restitution e is
