A ball bounce of 80% of its original height . What fraction of its mechanical energy is lost in each bounce ?

A ball bounce of 80% of its original height . What fraction of its mechanical energy is lost in each bounce ?

A ball bounces to 80% of its original height. Calculate the mechanical energy lost in each bounce.

A ball bounces to 75% of its original height. Calculate the mechanical energy lost in each bounce.

What is mechanical energy ? What are its two types ?

A ball is dropped onto a floor from a height of 10 m . If 20% of its initial energy is lost,then the height of bounce is

A ball is dropped onto a floor from a height of 10 m . If 20% of its initial energy is lost,then the height of bounce is

A ball of mass m is dropped from a height of 20 m . The ball loses 20 per cent of its kinectic energy in striking the ground . What will be the height to which the ball will bounce ? Where does this lost energy go ?
