Another mechanics question.

Quote:

In the figre the curve AB is a snow slope mounted on a frame used for ski jumping practice. Skiers start from rest at A, 30 metres above the horizontal ground and launch themseves into the air from B, 10 meters above the ground at 10 degrees. C is vertically below B and D is the point the skier will land if no air resistance/friction

Im guessing you use potential energy and kinetic energy to find V.

I then find V as 14m/s...

The answer is 35.5cm which im struggling to get.

The red part on the diagram is the projection.

Any help is appreciated.

Thanks :)
