A 0.150kg baseball traveling with a horizontal speed of 4.50 m/s is hit by a baseball bat and then moves with a speed of 34.7 m/s in the opposite direction. What is the change in the ball's momentum?
ap physics -
Mass * (34.7 + 4.5) kg*m/s
4.5 m/s is an extremely slow speed for the thrown ball (16.2 mph) . I doubt if it would reach home plate if thrown horizontally from the pitcher's mound.
Are you sure the speed was not 24.50 m/s?
