SUMMARY
The work rate of an escalator lifting a 50.0 kg woman from the bottom to the top can be calculated using the formula W = mg(hf - hi). Given that the escalator is 30.0 meters long and moves at a speed of 1.00 m/s, the height (h) can be derived from the length and angle of the escalator. The work done by the escalator is directly related to the gravitational force acting on the woman, which is 490 N (50.0 kg * 9.81 m/s²). The power output can then be determined by dividing the work done by the time taken to ascend.
