A pitcher throws a 0.126-kg baseball, and it approaches the bat at a speed of 32.6 m/s. The bat does 71.7 J of work on the ball in hitting it. Ignoring air resistance, determine the speed of the ball after the ball leaves the bat and is 29.6 m above the point of impact. i found that the initial KE is 310.36 and i'm not sure where to go from there can someone help? thanks!
