Question

A ball is dropped from height h1it rebound to a height h2. Find the values of coefficient of restitution

Answer 1

Answer:

When a ball is dropped from a height h₁, the velocity before reaching ground is

v=

2gh

1

When the ball rebounces to a height h₂, the velocity just after impact was

v

′

=

2gh

2

Coefficient of restitution

=

2gh

1

2gh

2

=

h

1

h

2

Hence,

option B is correct answer.
