If the baseball (mass = 145 g) stays in contact with the bat for 0.08 s and leaves the bat with a speed of 68 m/s, what is the average force acting on the ball?


F=ma
a=68/.08= 850m/s^2

Average Force=850*145=123250N

You units are incorrect. Your mass needs to be in kilograms for the answer to come out in Newtons.
