## Homework Statement

When its engine of power 76 kW is generating full power, a small single-engine airplane with mass 660 kg gains altitude at a rate of 2.8 m/s.

What fraction of the engine power is being used to make the airplane climb?

## Homework Equations

total power=76x10^3 W

mass=660 kg

dx/dt=velocity=2.8 m/s

Power=mass x velocity

## The Attempt at a Solution

(660x2.8)/(76x10^3) x 100 = 2.4% but this is wrong and im not sure where ive gone wrong
