A 108 kg man is skiing across level ground at a speed of 9.5 m/s when he comes to the small slope 1.2 m higher than ground level shown in the following figure. -8.0 m- f1.2 m (a) If the skier coasts up the hill, what is his speed (in m/s) when he reaches the top plateau? Assume friction between the snow and skis is negligible. m/s (b) What is his speed (in m/s) when he reaches the upper level if a 75 N frictional force acts on the skis? m/s
