A 60.0-kg skier with an initial speed of 12.0 m/s coasts up a 2.50-m high rise as shown. You can assume she starts exactly at the bottom of the rise, and the coefficient of friction between her skis and all surfaces is 0.80. (a) Find the work done by friction during the climb. (b) Find her final speed at the top. (c) Find the distance she travels along the top horizontal surface before she comes to rest.

    A skier, starting from rest, coasts down a slope that makes a 25.0o angle with the horizontal. The coefficient of kinetic friction between the snow and the skis is 0.200. The skier travels along the slope a distance of 11.4 m before skiing off the edge of a cliff. The skier falls a vertical distance of 3.80 m before landing on another downhill slope. Determine the speed with which the skier lands.

    A skier with mass 64.0 kg starts at rest at the top of an 842 m long ski slope, which makes an angle 13.0 ∘ with the horizontal. A typical coefficient of friction between skis and snow is 5.20×10−2. skiers don't go straight down the hill- they zigzag back and forth. Even though they still end up at the bottom of the hill, they've lost more energy to friction because friction is a non-conservative force. Let's say due to zigzagging,...
