Use the work–energy theorem to solve each of these problems
a skier moving at 5.99 m/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis.
a. how far does she travel on this patch before stopping?
b. suppose the rough patch in part a was only 2.85 m long. how fast would the skier be moving when she reached the end of the patch?
c. at the base of a frictionless icy hill that rises at 25.0∘ above the horizontal, a toboggan has a speed of 12.3 m/s toward the hill. how high vertically above the base will it go before stopping?

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
