An elevator and its load have a combined mass of 1550 kg. Find the tension in the supporting cable in Newtons when the elevator , originally moving downward at 11 m/s, is brought to rest with constant acceleration in a distance of 43 m.

Tension= mg + ma where a is the acceleration. + when the elevator is going up (it adds to tension), and  going down, it reduces tension when falling.
a= change velocity/time (rest means zero velocity)
