00-kg man is škiing across level ground at a speed of 14 m/s when he comes to the small slope 1.8 m higher than ground level shown in the following figure. -8.0 m 1.8 m a. If the skier coasts up the hill, what is his speed when he reaches the top plateau? Assume friction between the snow and skis is negligible. m/s b. What is his speed when he reaches the upper level if an 80-N frictional force acts on the skis? m/s v%3D
