A 55.6 kg ice skater is moving at 3.96 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.790 m around the pole. (a) Determine the force exerted by the rope on her arms. (b) What is the ratio of this force to her weight? (force from part a / her weight) A 2000 kg car rounds a circular turn of radius 20 m. If the road is flat and the coefficient of friction between tires and road is 0.75 , how fast can the car go without skidding? m/s

A loaded ore car has a mass of 950 kg and rolls on rails with negligible friction. It starts from rest and is pulled up a mine shaft by a cable connected to a winch. The shaft is inclined at 35.5∘ above the horizontal. The car accelerates uniformly to a speed of 2.25 m/s in 11.5 s and then continues at constant speed. (a) What power must the winch motor provide when the car is moving at constant speed? kW (b) What maximum power must the motor provide? kW (c) What total energy transfers out of the motor by work by the time the car moves off the end of the track, which is of length 1,250 m? J
