A 107 kg man is skiing across level ground at a speed of 11 m/s when he comes to the small slope h = 1.8 m higher than ground level of length d = 9 m as shown in the above figure.
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.
Answer:
b. What is his speed when he reaches the upper level if an 95 N frictional force acts on the skis?
Answer:
