Skills for analyzing processes using the work-energy principle
A cable lowers a 1200-kg elevator so that the elevator’s speed increases from zero to 4.0 m/s in a vertical distance of 6.0 m. What is the force that the cable exerts on the elevator while lowering it? Specify the system, its initial and final states, and any assumptions you made. Then change the system and solve the problem again. Do the answers match?
