An elevator's cable is cut causing the elevator to slide down thhe elevator shaft on the emergency brakes and wheels. Suppose that the mass of the elevator and passengers were 1500 kg, and the frictional force (wheels on tracks)was 9000N
Draw a force diagram
determine the acceleration of the elevator
