## Homework Statement

A Skier leaves the ramp at 25 degrees inclined from the horizontal. The ramp is 4 meters above the ground. The skier lands 100 meters away. The ground itself is sloped from the ramp relating to a 3 4 5 triangle. I need to find the initial velocity off the ramp and the extent of the skiers injuires

## Homework Equations

Range=(V^2/g)*sin2(theta)

Time of flight=(2V/g)sin(theta)

x=x(o) +V(o)T

## The Attempt at a Solution

I used the range equation to find the initial velocity which i found to be 35.78m/s and then used that in the TOF equation to find the TOF to be 3.08s and then split the velocity into its horizontal and vertical components to get V(x)=32.42m/s V(y)=15.15m/s

I then used V(x) in the x=x(o)+V(o)t to get the x distance to make sure my numbers were right and i got X= 99.8m which is basically 100m. Am I going about this right or right and did the fact that a 3 4 5 triangle was drawn under the 100m distance matter at all?
