A CRICKET BALL OF MASS 0.4kg MOVING WITH A VELOCITY OF 72km/h IS BROUGHT TO REST
BY A PLAYER . WHAT IS THE MAGNITUDE OF THE AVERAGE FORCE EXERTED BY THE PLAYER?
depends on how long it took to stop the ball, or how far it traveled while being stopped.
Surely you can see that a gentle push (small force) exerted over many meters would do the job, as would a strong force imparted in an instant.
