Answer 1

Answer:

1) 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.

2)The boat exerts an equal force in the forward direction which helps him to move forward. The force exerted by the boat is called reaction. So due to this reaction force the boat moves backward due to the force exerted by the man. So that's why if a man jumps out from a boat, the boat moves backward.
