Question

A ball falls on the ground from a height of 2.0 m and rebounds up to a height of 1.5 m. Find the coefficient of restitution.

Answer 1

Thanks for asking the question!

ANSWER::

u = √2gh which is velocity on ground when ball approaches the ground.

u = √(2 x 9.8 x 2)

v + Lu = 0                            v = velocity of ball when it separates from ground

Lu = -v

L = √(2 x 9.8 x 1.5) / √(2 x 9.8 x 2)

L = √(3/4)

L=√3/2

Hope it helps!
