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

The correct explanation for why the ball slows to a stop after rolling a short distance on a level ground is:
(c) There is a force on the ball opposing the motion.

Explanation:
– The ball experiences a force opposing its motion, known as friction, between the ball and the ground.
– Friction acts in the direction opposite to the ball’s motion, gradually reducing its speed until it comes to a stop.
– As the ball rolls on the ground, friction between the ball and the surface gradually dissipates its kinetic energy, bringing it to rest.

Why Other Options Are Incorrect:
– (a) The batsman did not hit the ball hard enough: This option does not directly relate to the slowing down of the ball due to friction.
– (b) Velocity is proportional to the force exerted on the ball: While this statement has some truth regarding acceleration (not velocity), it doesn’t explain the ball’s slowing down due to opposing forces.
– (d) There is no unbalanced force on the ball, so the ball would want to come to rest: This option is partially correct in stating that the absence of an unbalanced force leads to the ball’s tendency to come to rest, but it doesn’t directly address the opposing force of friction causing the slowdown.
