13. A 100kg man is skiing across level ground at a speed of 8m/s when he comes to the small slope shown. If the skier coasts up the hill, what is his speed when he reaches the top plateau? Assume friction between the snow and the skis is negligible. What is his speed when he reaches the upper level if an 80N frictional force acts on the skis? i 8.0m1 1.8 m
