An elevator cab of mass m= 250 kg is descending with an intialvelcioty of 2.0 m/s when its supporting cable begins to slip,allowing it to fall with constant acceleration a = g/10.
a) During the fall through the distance d = 24 m, what is the workW done on the cab by gravitional force F?
b) During the 24 m fall, what is the W done on the cab by the upwadpull T of the elevator cable?
