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
(a)the batsman did not hit the ball hard enough
(b)velocity is proportional to the force exerted on the ball
(c)there is a force on the ball opposing the motion
(d)there is no unbalanced force on the ball, so the ball would try to come to rest
