I can't seem to master this equation, because I think I'm doing things right and I'm not. 1. The problem statement, all variables and given/known data When a 410 baseball gram is hit, its velocity changes from +28.87 m/s to -22.34 m/s. The baseball is in contact with the bat for 56.10 milliseconds. You may assume that the balls outward velocity is antiparallel to its incoming velocity. What is the magnitude of the average force on the ball? 2. Relevant equations FΔt = mΔv 3. The attempt at a solution (0.410 kg)(-22.34 m/s - 28.87 m/s)/(0.0561 s) = F 374.3 N = F But this isn't correct. I messed up Δv before, did I do it again?
