Detailed Solution

The moving body can be stopped when a force is applied to it.
According to the second law of motion, force is defined as the rate of change of momentum per unit of time. Therefore, force is directly proportional to the change of momentum.
The more the change in the momentum more will be the more force applied.
Momentum is given as the product of mass and velocity.
The mass of a moving tennis ball is less than that of a cricket ball moving at the same velocity.
Thus the tennis ball has less momentum than the cricket ball, because of which it is easier to stop a tennis ball than a cricket ball moving with the same velocity.
