From potential energy, U = mgh, the mass of the elevator is:
The height from the earth's surface can be obtained by:
Look at this applet. It shows an elevator with a small initial upward velocity being raised by a cable. The tension in the cable is constant. The energy bar graphs are marked in intervals of 600 J.
Part A What is the mass m of the elevator? Use g=10m/s2 for the magnitude of the acceleration of gravity. Express your answer in kilograms to two significant figures.
