A skier, of mass 50 kg, pushes off the top of a hill with an initial speed of 5 m/s. Neglecting friction, how fast in m/s will he be moving after dropping 17 m in elevation? (Neglect friction, use g=10m/s2)

2. Relevant equations

GPE = MGH

KE =(1/2)mv^2

3. The attempt at a solution

KE = (1/2)mv^2

KE = (1/2)(50)(25)

KE = 625

GPE = mgh

625 = (50)(10)h

625 = 500h

1.25 = h

If he's only 1.25 meteres up, I can't drop him seventeen meters, so I know I'm doing something wrong. Please help.

Also. I'm sorry to post so often, but this homework is killing me.
