Q. Dan applies a force of 91N on a heavy box by using a rope held at an angle of 50° with the horizontal. What are the vertical and horizontal components of the 91.0 N forces?

Q. A 57 kg skier starts from rest at a height of H = 19 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28Â° with the horizontal. Ignore the effects of air resistance and assume the ramp is frictionless. What is the maximum height h of his jump above the end of the ramp?
