An experimental electrical generator collects sunlight with mirrors and generates heat at a rate of 1.2 megawatts. The generator is mounted on the roof of an environmentally friendly building and is used to operate an elevator. The elevator has a maximum operating load of 8000 kg and a maximum velocity of 6 m/s.
A. Determine the power that the generator must supply to operate the elevator at its maximum operating
B. What is the efficiency of this system?
