Homework Statement
A skier (m=61.00 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 6.70 m and D = 9.80 m, find H.
I already found the velocity as he leaves the cliff to be 29.2 m/s

Homework Equations
E[1] + W[non conservative] = E[2]
K= .5mv^2
U= mgh
The Attempt at a Solution
w[nc]= 0 (no friction)
K[1]= 0, U[2] = 0 so K[2] = U[1]
K[2]= .5*61*29.2^2
K[2]= 26005.52
26005.52 = mgH
26005.52/ (61*9.8) = H
H=43.5
