Answer:
Power delivered will be 10755.87 W
Step-by-step explanation:
We have given mass of elevator m = 591 kg
Time t = 4.79 sec
As the elevator starts from rest so initial velocity u = 0m/sec
Final velocity v = 2.17 m/sec
From first equation of motion
v=u+at. here v is final velocity, u is initial velocity and t is time
So


Height is given by

As elevator moves upward and acceleration due to gravity is downward so net acceleration due to gravity is downward so net acceleration = g-a=9.8-0.453 = 9.347

Now work done

We know that power
