A baseball hits the catcher’s glove with a horizontal velocity of 55m/s. The mass of the baseball is 0.15kg. The displacement of the ball due to the deformation of the catcher’s glove and the movement of the catcher’s hand is 23cm from the instant the ball makes contact with the glove until it stops. a. How much kinetic energy does the baseball have just before it strikes the glove? b. How much work does the catcher have to do to the ball during the catch and is it positive or negative? c. What is the average impact force exerted by the glove on the baseball? Answer parts a-c. Include units and direction.
