A metal ball falls from a height of 1m on to a steel plate and jumps upto a height of 81 cm. The coefficient of restitution of the ball and steel plate is

0.2

0.9

Text Solution

Verified by Experts

The correct Answer is:

`e=("Velocity of sepration")/("Velocity of approach")`
`e=sqrt((h_(2))/(h_(1)))=sqrt(81/100)=0.9`
Hence the value of coefficient of restitution is 0.9
