## Homework Statement

Pleaseeee someone help me with this.. its literally hurting my brain

A baseball with mass 0.152kg is moving horizontally at 32.0m/s[E] when it is struck by a bat for 0.00200 seconds. The velocity of the ball just after the collision is 52.0m/s [W20°N]

a)find the impulse experienced by the ball.

b)find the average net force of the ball

## The Attempt at a Solution

someone in my class told me to get the answer we do the following:

a) I=(m)Δv =0.152(32-(-52))=12.768 (kgm/s) [assume East direct is positive]b) I=FΔt, so F=I/Δt=12.768/0.00200=6384 (N)

part b) I understand..

where I'm lost is the logic in part a)'s answer..

can someone please explain to me if I'm doing that right? It's confusing me because of the part in red..

At least I thought that you can't just add two vectors when they aren't parallel
