Gerry, who weighs 500 newtons, is late for class. It takes her 7.5 seconds to run up two flights of stairs, a total height of 8.0 meters. How much power does Gerry expend in her run upstairs?

Power = Work/Time
= W*H/T
W is her weight and H is the height climbed. T = 7.5 s.
The answer will be in watts.
