Answer
The average force exerted by the ball on the glove is 296 N.
Work Step by Step
Let's calculate the kinetic energy of the ball.
$KE = \frac{1}{2}mv^2$
$KE = \frac{1}{2}(0.145 ~kg)(32 ~m/s)^2$
$KE = 74 ~joules$
The work done by the glove on the ball is equal to the kinetic energy of the ball.
$Work = Fd$
$Fd = KE$
$F = \frac{KE}{d}$
$F = \frac{74 ~J}{0.25 ~m}$
$F = 296 ~N$
The average force exerted by the glove on the ball is 296 N, and by Newton's Third Law, the average force exerted by the ball on the glove is 296 N.
