Question

On a moving vehicle, you want to drop a ball into a drown circle on road such that it remains there even after few bounces. When should you throw the ball?​

Answer 1

Answer:

When an object takes a turn two forces come to act.

1. centripetal force

2. centrifugal force

Centripetal force acts inward (towards the centre of the circular turn). This is provided by the frictional force. When the speed is large, required centripetal force to stay in the circular path increases. But friction is unable to provide large centripetal force and hence the body is thrown outwards.

Answer 2

the vehicle is a closed system so unless the vehicle itself doesn’t change speed or direction it is the same as if the vehicle was stationary.
