A ball is dropped on a floor from a height of `2.0m`. After the collision it rises up to a height of `1.5m`. Assume that `40%` of the mechanical energy lost goes as thermal energy into the ball.Calculate the rise in the temperature of the ball in the collision. Heat capacity of the ball is `800J K^(-1)`

`0.5xx10^(3).^(@)C`

`1.0xx10^(3) .^(@)C`

`1.5xx10^(3) .^(@)C`

`2.5xx10^(3) .^(@)C`

Text Solution

Verified by Experts

The correct Answer is:

`W=JHimplies(40)/(100)(mgh)=JmSDeltaT`
