A61 kg skier on level snow coasts 184 m to a stop from a speed of 12 m/s. (a) use the work-energy theorem to find the coefficient of kinetic friction between the skis and snow. (b) suppose a 75 kg skier with twice the starting speed coasted the same distance before stopping. find the coefficient of kinetic friction between that skier’s skis and the snow.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great. d) about 10 times as great.
