An extreme skier takes off from a jump and is going for height. If she leaves the jump traveling 15 m/s, and is traveling 11.9 m/s as she reaches the top of her flight, how high does she get above the top of the ramp? Assume g ≈ 10 m/s2.

A playful Jack Russel Terrier named "Sally, the Lord of Destruction" is spending the afternoon sitting in her favorite cardboard box. Unbeknownst to her, her nemesis, the giant red ball, is preparing to strike. The 8 kg red ball begins rolling from rest at the top of an 8 meter tall hill, as shown (it rolls down the hill without frictional losses). Upon reaching the bottom of the hill, the big red ball crashes into Sally's box, sending Sally (and her box) forward towards a cliff. Sally and her box together have a mass of 15 kg, and immediately after the collision, the ball bounces backwards off the box, with a velocity of 5 m/s. As Sally is propelled forward, the box immediately begins sliding up a 1 meter tall incline (inclined at 60∘ ) with coefficient of friction of 0.3 (assume the box does not slide over horizontal ground at all, it immediately begins going up the incline). Sally and her box fly off the cliff, but land safely in a kiddie pool filled with tapioca pudding (Sally put it there, since she suspected the giant red ball might attack her). If she lands 4 meters below the spot she left the cliff, how far horizontally did she fly?

A skier leaves the ramp of a ski jump with a velocity of v = 15.0 m/s, θ = 14.0∘ above the horizontal, as shown in the figure. The slope where she will land is inclined downward at ϕ = 50.0∘, and air resistance is negligible. (a) Find the distance from the end of the ramp to where the jumper lands. m (b) Find the velocity components just before the landing. (Let the positive x direction be to the right and the positive y direction be up. vx = m/s vy = m/s (c) Explain how you think the results might be affected if air resistance were included?
