1. The problem statement, all variables and given/known data herman(m=135kg) is sitting motionless on a tire swing. eddie hits a baseball (m=2kg) and v=169 m/s. L=3.2m. (A)what is the velocity of the ball after the collision and (B) what is the velocity of herman after the collision. (C) what is herman's change in KE. (D) eddie hits another ball and this time herman catches it. as a result herman moves a height h, how fast was the ball going this time? 2. Relevant equations p(0)=p(f), KE=1/2mΔv^2, p=J=mgh=mv 3. The attempt at a solution. (A and B) i started out with my p(0)=p(f), but i have two unknown velocities so iam not sure where to go from there? i think for C, i can just use the found velocities to find the change in KE. For the last one i know that h=l-lcos(theta) so i plugged that into mgh=mv. thanks for help!
