What is the average force exerted by the ball on the glove, and how do you show the work?

Question

A baseball (m=140 g) traveling 32 m/s moves a fielders glove backwards 25 cm when the ball is caught. What was the average force exerted by the ball on the glove

Answer 1

Asking for average force implies that the force exerted by the catcher to stop the ball is not constant. One more datum is required for a solution. Is gravity to be ignored? If not what is the angle of descent of the ball when it hits the glove?

Assuming constant acceleration, and thus constant force,
and ignoring gravity,
F =ma = mv^2/(2s) =
(0.140 kg)(32 m/sec)^2)/(2*0.25 m)

Answer 2

what is the time span???
