Question

A baseball with a mass of 0.165 kg travels toward the outfield at a speed of 47 m/s. The outfielder’s glove brings the ball to rest in 0.20 s. What is the average force exerted on the ball by the glove?

Answer 1

Answer:

38.775N

Explanation:

A=(f-i)/t, where a=acceleration, f=final velocity, i=initial velocity, and t=time

A=(0-47)/0.2

A=-47/0.2

A=-235m/s^2

Use that acceleration and plug it into this equation

F=ma

F=0.165*-235

F=-38.775N

The glove exerts an equal and opposite force on the ball of 38.775N of force.
