**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.
