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 actual 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 m/s/s.

Answer;

= 90600 m/s...

Explanation;

velocity of ball = 96 mi/hr = 42.916 m/s...  

velocity of bat = -56mi/hr = -25.034m/s.. ( note the negativity here..)  

time = 0.75 millisec = 0.75 * 10^-3 sec  

acceleration = (velball - velbat) / time

                     = (42.916 - (-25.034)) / (0.75 * 10^-3)

                     =90600 m/s

answer: good job it's all correct !
