omg im so lost for this question, look at this video first http://mp.pearsoncmg.com/probhtml/applets/setup5_5_3.html 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. Question: Find the magnitude of the tension T in the cable. Be certain that the method you are using will be accurate to two significant figures.
