[Friction] A 100. kg skier is going across level ground at a speed of 8.0 m/s when he comes to a small slope 1.8m higher than their current level as shown below. a) If the skier coasts up the hill, what is their speed on the upper plateau if we ignore friction? b) If instead we exert an 80. N kinetic friction force on the ramp what is the upper speed now?
