A 0.143 kg baseball, thrown with a speed of 44.6 m/s, is hit straight back at the pitcher with a speed of 53.0 m/s. (a) What is the magnitude of the impulse delivered by the bat to the baseball? Momentum is a vector. When the baseball changes direction, the direction of the momentum changes, too. Make sure you take this into account when you find the change in momentum. In other words, one of the momenta should be negative, and the other should be positive. kg · m/s (b) Find the magnitude of the average force exerted by the bat on the ball if the two are in contact for 1.92 x 10-3 s.
