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?
