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?
total power=76x10^3 W
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
