Answer 2

Reason ↓

While catching a ball, a cricket player lowers his hands, because by doing so, he increases the time of catch. That is, the person increases the time to bring about a given change in momentum, and hence rate of change of momentum decreases. Thus, a small force is exerted by ball on the hands.

Newtons 2nd paw of motion give us a method to measure the force acting on an object as a product of its mass and acceleration.

F=MA ( force = mass* acceleration )
