A fully loaded elevator weighing 2000 lbs accelerates upward from rest, attaining its rated velocity of 20 fps upon reaching a height of 25 ft. Solve for the tension on the cable lifting the elevator. What is the minimum required power of the lifting motor if 10% is allowed for friction?

I tried to solve this. I was not able to solve it. I don't know where I will start.
