$A$ batsman hits a cricket ball which then rolls on a level ground. After covering a short distance,the ball comes to rest. The ball slows to a stop because
- Athe batsman did not hit the ball hard enough.
- Bvelocity is proportional to the force exerted on the ball.
- Cthere is no unbalanced force on the ball,so the ball would want to come to rest.
- Dthere is a force on the ball opposing the motion.
