find change in momentum .145(27+32)
force = change in momentum/time
= change in momentum /(1.5*10^-3 )
A 0.145- kg baseball with an initial speed of 27 m/s rebounds with a speed of 32 m/s after being struck with a bat. If the duration of contact between ball and bat was 1.5 ms, what was the magnitude of the average force between ball and bat?
