A 72.5-kg skier coasts up a snow-covered hill that makes an angle of 22.9 ° with the horizontal. The initial speed of the skier is 8.71 m/s. After coasting a distance of 1.19 m up the slope, the speed of the skier is 3.74 m/s. (a) Find the work done by the kinetic frictional force that acts on the skis. (b) What is the magnitude of the kinetic frictional force?
Choose the Correct Answer: 1. A skier leaves a ski jump with a horizontal velocity of 27.0 m/s (and no vertical velocity component). The skier lands 2.50 seconds later. What is the magnitude of the skier's displacement during the jump (a) 67.5 m (b) 98.2 m (c) 74.1 m (d) 30.7 m 2. The x and y positions (in meters) of a particle are given by: x(t) 253 t, and y(t)-12.0 t2+ 155 t100. The speed of the particle at...
