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...
