**[SOLVED] linear motion**

## Homework Statement

Skiers leave a ski jump at 28 m/s, at an angle of 9.5 degrees below the horizontal. Their landing zone is a horizontal distance of 55 m from the end of the jumo The ground is contoured at that point so that the skiers trajectories make an angle of only 3 degrees with the ground on landing. What is the slope of the ground in the landing zone?

## Homework Equations

tan theta = y/x

x = x0 + v0t + 1/2gt^2

y = y0 + y0t + 1/2 gt^2

## The Attempt at a Solution

t = (x - x0)/v0 = (x - x0)/v0cos9.5 = 2s

From here I can solve for the velocity vector at the landing, but I do not see how to solve for the x-y coordinates
