A clear explaination is greatly appreciated

**drwls**, Saturday, February 5, 2011 at 6:34amKinetic energy of M*g*H is lost, with H = 2.0 m.

The initial Velocity is

V1 = 7.0 m/s

The final kinetic energy is

(1/2) M V2^2 = (1/2) M V1^2 - M g H

Cancel out the M's and solve for the final velocity V2.

V2^2 - V1^2 = -2 g H
