## Homework Statement

A baseball with a mass of 0.152 kg is moving horizontally at 32.0 m/s [E], when it is struck by a bat for 0.00200 seconds. The velocity of the ball just after the collision is 52.0 m/s [W 20⁰ n].

a) Find the impulse experienced by the ball?

b) Find the average net force of the ball?

## Homework Equations

J = F ∙ ∆t

F ∙ ∆t = m ∙ ∆v

## The Attempt at a Solution

I've done my work like it says in the text book and it's easy to do when I see examples of similar problems but I still haven't completely wrapped my head around it and I'm not sure why it's right...

Can you please check it over and describe what's going on?

Thank you,

Julian
