An estimated force vs. time curve for a baseball struck by a bat is shown in the figure below. Fmax = 18 000 N F (N) 20000 15 000 10000 5 000 t (ms) 1 2 (a) From this curve, determine the impulse delivered to the ball. 13500 Your response is off by a multiple of ten. N ·s (b) From this curve, determine the average force exerted on the ball. 9000 Your response is off by a multiple of ten. kN
