## Homework Statement

A ski jumper acquires a speed of 119.0 km/hr by racing down a steep hill. He then lifts off into the air from a horizontal ramp. Beyond this ramp, the ground slopes downward at an angle of θ = 45 degrees.

## Homework Equations

Assuming the skier is in free-fall motion after he leaves the ramp, at what distance d down the slope does the skier land?

## The Attempt at a Solution

I converted 119.0 km/hr to m/s, so 33.055 m/s

I then try to find the horizontal range: 0=33.055^2 + 2*9.8*X and found X=55.74m

55.74cos45=78.83m down the ramp.

What have I done wrong?
