Baseball Problem - Determine Speed of Ball After Impact

[leezak]

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!

Break up the kinetic energy in order to get the initial velocity. Use the kinematic equations to solve the rest.
