1. The problem statement, all variables and given/known data To warm up for a match, a tennis player hits the 58.0g ball vertically with her racket. If the ball is stationary just before it is hit and goes 5.50m high, what impulse did she impart to it? I know that the answer is 0.602 kgm/s but I don't understand why this is the answer 2. Relevant equations P=mv ptotal = Pinitial + Pfinal 3. The attempt at a solution Pinitial = (0.058kg)(0 m/s) = 0 Pfinal = (0.058kg)(vfinal I'm not sure where to go from here. I think that kinitial+Uinitial = kfinal+ufinal has something to do with it But I'm not sure.
