A 3,647 KG elevator is pulled upward by a constant tension force. The elevator starts at rest and under the influence of this constant tension force, accelerates upwards so that its speedis 6.82 m/s when it located 6.0 m above its initial location. What is the average power that the tension in the cable exerts on the elevator? Assume that the only force acting on the elevator is gravity. Write your answers in kW (kilo-watts) to three significant figures. (Hint: how long does it take for the situation to occur?
What’s the ratio of the instantaneous power exerted on the elevator by the tension in the cable when the elevator’s height is 2.74 m above its initial point tit he average power calculated in the question above? Write your answers to three significant figures( Hint you can use your calculations of the energy transferred to the elevator by the cable to determine the magnitude of the tension force)
