h= 52m

* theres an arrow for g pointing down.

**drwls**, Thursday, February 11, 2010 at 1:06amThe time to fall (t) can be computed using

(1/2) g t^2 = 52 m

The final speed can be calculated by realizing that the kinetic energy increases by M g H. That means that

V^2 increases by 2 g H.

Vfinal^2 = 18^2 + 2*9.8*52
