A skier goes down a 200 m slope. (a) If his altitude changes by 80 m during the run, what is his speed at the bottom if there is no friction? (b) If the skier’s mass is 70 kg and his final speed is actually 15 m/s, find the average force exerted by friction. (You don’t need to know the detailed shape or angle of the slope
