Question

A ball of mass 'm' is allowed to roll down an inclined wooden plane from a

certain height 'h'. At the foot of the inclined plane it moves a certain distance 'S'

over a plane glass sheet. What would you suggest to decrease the distance 'S'

covered by the ball on the plane glass sheet and why?​

Answer 1

Explanation:

The marble will move shortest on the floor covered with sand. Sand will allow more friction between marble and floor making it hard to move longer.
