Suppose a 1350-kg elevator car is lifted a distance 41 m by its cable at a constant speed, assuming the frictional force on the elevator has a constant value of 1575 N. Calculate the work done on the elevator by its cable, in joules. Calculate the work done by the gravitational force on the elevator, in joules, during this process. Calculate the total work done on the elevator, in joules.

A 1500-kg air conditioning unit is being lifted by a crane onto the roof of a building. The unit starts on the ground and is raised straight up to a height of 12.0 m by a cable attached to the crane. The tension in the cable during the lift is 1.54 × 104 N. (Reminders: a free body diagram will probably be helpful, and work can be positive or negative.) (a) How much work is done on the air conditioning...
