(The remainder is used to overcome the effects of air resistance and of inefficiencies in the propeller and engine.) Express your answer as a percentage using two significant figures. Submit Provide Feedback Next >Explanation / Answer
As we know that;
Power used for climbing is;
= p= F*v = m*g*V
= (670*9.8*2.9) = 19041W
= 19.041kW
Then
Required fraction is 19.041/70 = 0.272
Fraction in percentage is ,
= 0.272*100
= 27.2% of the engine power is used for climbing
