Question

A batman hits a cricket ball, which then rolls on a level ground. After covering a short distance, the ball comes to rest. The ball slows down to stop because

• A. The batman did not hit the ball hard
• B. Velocity of ball is proportional to force acting on it
• C. There is force on the ball opposing its motion
• D. There is no unbalanced force on the ball and hence comes it to rest

Answer 1

The correct option is C

There is force on the ball opposing its motion

1. There is a force on the ball opposing the motion.
2. The ball comes to rest because there is a force of friction that acts in the opposite direction of the motion of the ball.
3. Friction is a force that prevents, or tries to prevent, the slipping or sliding of two surfaces in contact.
4. When the ball rolls on the flat surface of the ground, its motion is opposed by the force of friction (the friction arises between the ground and the ball).
5. This frictional force eventually stops the ball.

Hence, option C is correct.
