1. The problem statement, all variables and given/known data A pitcher throws a 0.124-kg baseball, and it approaches the bat at a speed of 54.2 m/s. The bat does Wnc = 76.5 J of work on the ball in hitting it. Ignoring the air resistance, determine the speed of the ball after the ball leaves the bat and is 21 m above the point of impact. 2. Relevant equations W = E - E0 3. The attempt at a solution W = E -Eo 76.5=.5(.124)v2-.124(9.8)21 102.0192=.062v2 v = wrong answer! Please help. I dont have a basics in physics, so please explain from an beginners standpoint. Thankyou!!!
