Problem: A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at a speed of 60.0m/s , and it leaves the bat traveling to the left at an angle of 40 degree above horizontal with a speed of 55.0m/s. The ball and bat are in contact for 1.75ms.
Part A: Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right.
Part B: Find the vertical component of the average force on the ball. The positive y-axis points upwards.
