Question

A baseball (m=140g) traveling 32m/s moves a fielders

glovebackward 25cm when the ball is caught. What was the average
forceexerted by the ball on the glove?

Answer 1

Average force, F = 286.72 N

Step-by-step explanation:

Given that,

Mass of the baseball, m = 140 g = 0.14 kg

Speed of the ball, v = 32 m/s

Distance, h = 25 cm = 0.25 m

We need to find the average force exerted by the ball on the glove. It is solved using the conservation of energy as :

`(1)/(2)mv^2=mgh`

F = mg

`(1)/(2)mv^2=Fh`

`F=(mv^2)/(2h)`

`F=(0.14* (32)^2)/(2* 0.25)`

F = 286.72 N

So, the average force exerted by the ball on the glove is 286.72 N. Hence, this is the required solution.
