A ball is released from the point P and moves along an inclined plane and then along a horizontal surface as shown Class 8

A ball is released from the point P and moves along an inclined plane and then along a horizontal surface as shown in the Fig. 5.16. It comes to stop at the point A on the horizontal surface. Think of a way so that when the ball is released from the same point P, it stops (i) before the point A (ii) after crossing the point A. Class 8

Answer:

(i) To stop before point A: You could increase the friction on the horizontal surface by using a rougher material or adding a small incline that leads upwards, which would slow the ball down more effectively.

(ii) To stop after crossing point A: You could decrease the friction on the horizontal surface by using a smoother surface or adding a slight downward slope after point A, which would allow the ball to continue moving past point A before eventually stopping.
