Concept

Problem: An elevator of mass m rises a vertical distance h with upward acceleration equal to one-tenth g. Find an expression for the work the elevator cable does on the elevator.

FREE Expert Solution

Work done on the elevator by the cable is:

W=fh, where f is force and h is the vertical distance.

The force of gravity is expressed as:

f=mg, where m is mass and g is the acceleration due to gravity.

Newton's second law:

F=ma
