Question

A baseball (m=145g) traveling 39 m/s moves a fielder's glove backward 23 cm when the ball is caught.

Answer 1

The average force exerted by the ball on the glove is 480 N.

What is the force exerted by the ball on the glove?

The average force exerted on the glove by the ball is equal in magnitude to the force on the ball.

• Force = mass * acceleration

mass = 145 g = 0.145 kg

Acceleration of the baseball, a = (v² - u²)/2s

where:

v is final velocity = 0

u is initial velocity = 39 m/s

s is distance = -23 cm = 0.23 m

a = (0 - 39²)/2(-0.23)

a = 3306.52 m/s²

Force = 0.145 * 3306.52

Force = 479.4 N

Average force = 480 N

In conclusion, force is derived from the product of mass and acceleration.
