Concept

Problem: 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.

From potential energy, U  = mgh, the mass of the elevator is:

m=Ugh

The height from the earth's surface can be obtained by:

h=y4=44
