1. The problem statement, all variables and given/known data Calculate the work done by a 52.98 kg person, who climbs a set of 0.20 m tall stairs (starting from rest) in 2.96s. Calculate the power required to achieve this. 2. Relevant equations w=F•d 3. The attempt at a solution My issue with this question has been identifying the force which is acting in the situation. I know that Fg applies (mass • 9.81 m/s) and that there must be an applied force of some sort because the person is moving (working against gravity, I suppose?), but I am not sure which information I should use to calculate the "F" variable in the w=F•d equation. I think they want the power in watts (Joules per second).
