Asked by katie
A 0.130kg baseball pitched at 35.5 m/s is hit on a horizontal line drive straight back at the pitcher at 50.5 m/s .
Part a: If the contact time between bat and ball is 4.25×10^−3 , calculate the magnitude of the force (assumed to be constant) between the ball and bat.
part b)Determine the direction of the force exerted on a ball.
a)the force is directed towards the pitcher
b) the force is directed away from the pitcher.
