Question

A steel ball of mass hundred KG is dropped from a height of 40 m on a steel ball plate fixed on the surface of the earth the steel ball after striking the steel plate rebounce to height of 20 m calculate the coefficient of restitution

Answer 1

Answer:

e=h2/h1

→e=20/40=0.5

Explanation:

hope it was helpful

Answer 2

hey mate...

here is your answer...

Coefficient of restitution:

e=h2/h1−−

√  =20/40

√  =1/2

√  =0.71
