Q. A 58 kg skier starts from rest at a height of H = 18 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless.

Q. A mass of 1.70 kg stretches a vertical spring 0.313 m. If the spring is stretched an additional 0.130 m and released, how long does it take to reach the (new) equilibrium position again?
