1.) A 2000 kg car with a maximum power output of 180 horsepower is driving up a 4 oslope at a constant speed of 22 mph. What percentage of the car's maximum power output is being used? Use the conversion: 1 hp = 745.7 W = 745.7 J/s. 2.) A 185 cm tall weightlifter performs an overhead press with 120 kg of weight. During the press, she lifts the weights from her feet (y = 0 m) to an unknown distance above her head. If she outputs 2800 J of energy during the lift, how high does the weightlifter lift the weights, relative to her head? 1.)
