In 2.97 minutes, a ski lift raises four skiers at constant speed to a height of 131 m. The average mass of each skier is 69.6 kg. What is the average power provided by the tension in the cable pulling the lift?
Homework Answers
Pavg = U/t
U = mgh
t = 2.97 min = 2.97 *60 s
Pavg = 69.6 * 9.8 * 131 / (2.97 * 60)
Pavg = 501.42 W

A crane is being used to lift a container onto a cargo ship. You need to program the crane so that it lifts the container with a constant positive acceleration, a, during the first half of the lift and with a constant negative acceleration of the same magnitude, -a, during the second half of the lift. You want to do this so that the maximum speed of the container during the lift is 7.85 m/s. The containers are initially at...
