Question

A metal ball falls from a height i m onto a steel plate and jumps up to a height of0.81 m. Find the coefficient of restitution.

Answer 1

Since v = √(2as) = √(2gs) here g = 9.8 m/s^2

v for a 1m fall is √19.2

v for a .81m bounce is √(.81 x 19.2) = 0.9√19.2

so, the coefficient of restitution is 0.9

i hope it will help you
