Help in physics question

In a flying ski jump, the skier acquires a speed of 110 km/h by racing down a steep hill and then lifts off into the air from a horizontal ramp. Beyond this ramp, the ground slopes downward at an angle of 45◦. (a) Assuming that the skier is in a free-fall motion after he leaves the ramp, at what distance down the slope will he land? What is his displacement vector from the point of ‘lift off’?

Produce two equations:

1) Straight line in the form y = mx + c representing the ground slope

2) Choose a SUVAT equation for the skiers vertical velocity vector and then define a general equation for the y displacement with a constant horizontal component of 110 km/hr

3) Solve simultaneously
