1. The problem statement, all variables and given/known data Consider the following two scenarios. (A) A pitcher throws a ball at -55m/s and the batter swims at 25m/s. (B) A pitcher throws a ball at -25m/s and the batter swings at 55m/s. The ball has a mass of 0.15kg and the bat has a mass of 1kg. Assume that the impact between the ball and the bat lasted for 0.3s, the coefficient of restitution was 0.5 and that the force of impact maintained a constant value throughout impact. Question a) For both scenarios: what impulse was exerted on the ball by the bat? Question b) For both scenarios: how much work was done on the ball by the bat? 2. Relevant equations ΣFΔt=mΔv W=FΔd 3. The attempt at a solution I thiiiink that I got question a) (A) ΣFΔt=mΔv ΣFΔt=(1)(25) ΣFΔt=25Ns (B) ΣFΔt=mΔv ΣFΔt=(1)(55) ΣFΔt=55Ns I am unsure of how to go from impulse to calculate work in question b).
