At-bar tow is required to pull 85 skiers up a 600 m slope inclined at 15° above horizontal at a speed of 2.5 m/s. the coefficient of kinetic friction is 0.06. find the motor power required if the mass of the average skier is 60 kg.

What is the main difference between the formulas for kinetic energy (ke) and gravitational potential energy (pe)? a. ke depends on position and pe depends on motion. b. ke depends on motion and pe depends on position. c. both energies depend on motion, but only ke depends on position. d. both energies depend on position, but only pe depends on motion.
