A pitcher throws a 0.140-kg baseball, and it approaches the bat at a speed of 40.0m/s. The bat does nonconservative W=70.0J on the ball in hitting it. Ignoring air resistance, determine the speed of the ball after the ball leaves the bat and is 25.0m above the point of impact.
Please give me some hints to do it!!THANKS THANKS THANKS!!!
