Andy ( still 85.0 kg), hits the jump ( at point C, which is 30 meters above the ground) with a speed of 25.0 m/s . If he lands the trick( at the point E, which is on the ground) with a speed of 28.0 m/s, what was the efficiency of the jump ? ( Andy starts at point A, which is 100 meters above the ground).

b) If Andy started down the hill( at point A) with a velocity and reached point C with a velocity of 25.0 m/s, what was the average force of friction acting on Andy as he traveled down the hill from point A to point C ? The angle of the hill between point A and C is exactly 45.0 degrees.

C) If it takes a 2500 W chairlift 1.00 minutes to lift Andy back up to the top of the mountain ( At point A), what is the efficiency of the motor ? Assume that the output energy is Andy's gravitational potential energy at point A.
