Question

Homer Agin leads the Varsity team in home runs. In a recent game, Homer hit a 96 mi/hr sinking curve ball head on, sending it off his bat in the exact opposite direction at 56 mi/hr. The actually contact between ball and bat lasted for 0.75 milliseconds. Determine the magnitude of the average acceleration of the ball during the contact with the bat. Express your answer in both mi/hr/s and in m/s/s. (Given: 1.00 m/s = 2.24 mi/hr)

Answer 1

acceleration is the change of velocity per time. Yout v change is 96-(-56) = 152.
It happened in 0.75 ms = 0.00075 s .So in mi/hr/s it would be 152/0,00075 mi/h/s

Answer 2
