1. The problem statement, all variables and given/known data When tossed upward and hit horizontally by a batter, a .24kg softball recieves an impulse of 2.7 N*s. With what horizontal speed does the ball move away from the bat? 2. Relevant equations Here are all the equations that were in our notes for this section. p (momentum) There was triangle P and triange t in my notes, so I wrote "change in" p=mv f=ma f*"change in"t="change in"p f*"change in"t=mvf-mvi "change in" P=mvf-mvi 3. The attempt at a solution I really was not sure what equation I should use because I didnt really know what the impulse was. I chose f*"change in"t=mvf-mvi. 2.7 N*s= (.24kg)(0m/s)-(.24kg)(v) I got v=-11.25m/s. I know this was wrong, but Im not sure which equation I was supposed to use or if I entered the information correctly in to the equation. Any help would greatly be appreciated.
