1. The problem statement, all variables and given/known data
In 1979 the human powered Gossamer Albatross flew across the English Channel. The pedalling pilot averaged 190 W over the distance. If the pilot's power was used to lift a 110 kg mass, to what height would he lift the mass in a time of 25 s?

2. Relevant equations
P = W/T
W=FxD

3. The attempt at a solution
All I am looking for is the formula to solve this question.
P = 190 J/S
M = 110 kg
Time = 25 s

How to find the height?

How much work would he have done during this period?
Lifting a mass up ... what happens to its energy?

Work = F x D

F=mg
F=110 x 9.8
F=1078 N

But how do we find the distance?

190 W is a quantity of power. Check out the definition (and units) of power.

Use the power rating to calculate the amount of work that the pilot will do during the stated period of time.
