pls answer this question

Answer 1

A cricketer moves his hand back because of the force and pressure of the ball exerted on the cricketer's hand

Answer 2

For the first question,light rifle will hurt the shoulder more than the heavy rifle because heavy rifle has more mass rather than light rifle, so due high mass the pressure(force) will be less and light rifle will give more opposite pressure(force) due to less mass rather than heavy rifle.

for second question,the cricket player moves his hands backwards while catching the ball because it helps to reduce the momentum of ball as the distance increases that makes easy to catch the ball.
