Homework Statement
A bird can fly in still air at 100km/h. The wind blows at 90km/h from W(x degrees)S. The bird wishes to return to its nest which is due E of its present position. In which direction, relative to the air, should it fly?My textbook says that the velocity of the bird relative to the air (bVa)= 100km/h. But this is in still air,whereas the wind is actually moving at 90km/h. So how is 100km/h= bVa?
