A ball is dropped from a heighth on a floor of coefficient of restitution e. the total distance coverewd by the ball just before second hit is

A

`h(1-2e^(2))`

B

`h(1+2e^(2))`

C

`h(1+2e^(2))`

D

`he^(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
Total distance ,`H=h+2h_(1)= h[1+2e^(2)][thereforeh_(1)=he^(2)]`
