A stationary elevator and its contents have a combined mass of 2000 kg. The elevator is suspended by a single

cable. (Assume 3 significant digits.)

(a) Draw a free-body diagram of the elevator and calculate the values of all the forces that are acting on it

when at rest.

(b) If the elevator is ascending at a speed of 4.0 m/s, what are the values of the forces acting at this point?

(c) If the elevator is descending at 4.0 m/s2

, what are the values of all the forces acting at this point?
