Question

A catcher “gives” with the ball when he
catches a 0.179 kg baseball moving at
16.5 m/s.
If he moves his glove a distance of 2.25 cm,
what is the average force acting on his hand?
Answer in units of kN.

Answer 1

Force x distance = work done by ball = kinetic energy reduction

F = (1/2) M V^2/0.0225 m

The force will be in Newtons. Convert to kN
