To predict the flying speed of an eagle, we can use the relationship between the flying speed (vv) and the mass (mm) of birds. It has been reported that in steady flight, the flying speed of birds is related to their mass as vv xmm-1/4. If a 4 kg bird flies at a speed of 75 km/h, how fast a 2 kg eagle do you expect to fly in km/h? Is your answer reasonable?
