Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Would you please help me with this problem.

A batter hits a baseball 1.2 meters above the ground (the point of impact). The ball has mass m = .14g

Speed V(initital) before the ball hit the bat is 40 meters/sec. The bat does 70 Joules of work on the ball in hitting it. Find the speed of the ball after the ball leaves the bat. The ball reaches a height of 25 meters above the point of impact.

Thank you,

Le
