Question

I am needing assistance with this question in its entirety. I have already submitted this question 2x and both answers were different and incorrect.

***Please type your answer or write in print, because I have had great difficulty with understanding most handwritten assistance done in cursive or mixed print/cursive.

(a) Find the useful power output (in W) of an elevator motor that lifts a 2700 kg load a height of 35.0 m in 12.0 s, if it also increases the speed from rest to 4.00 m/s. Note that the total mass of the counterbalanced system is 10,000 kg-so
that only 2700 kg is raised in height, but the full 10,000 kg is accelerated. (Enter a number.)
(b) ..W.hat.does it.cost (in cents), if electricity is $0.0900 per kW · h? (Enter a number.)
