[SOLVED] Fat: the fuel of migrating birds
Consider a bird that flies at an average speed of 10.7 m/s and releases energy from its body fat reserves at an average rate of 3.70 W (this rate represents the power consumption of the bird). Assume that the bird consumes 4g of fat to fly over a distance d without stopping for feeding. How far will the bird fly before feeding again?
Express your answer in kilometers.
First of all, this is an extremely weird question. And as always i find myself stuck. Anyone can give me a hint as to how i would approach this thing?
____
i know power = change in work / change in time = 3.7 ... and that work = FDcos(theta)
