1. The problem statement, all variables and given/known data A 65 kg student jogs upstairs from the first floor to the sixth, a vertical distance of 17.6 m, in 65 s. Find the power the student expends working against gravity (In kW.) 2. Relevant equations F=m*A W=F*d P=W/t 3. The attempt at a solution Tried solving here but didn't know how to incorporate gravity into this, got a crazy answer.
