Question

A pilot wants to fly west (ie., the resultant is west). If the plane has an airspeed of 9.5 m/s, and there is a 25m/s wind blowing north, in what direction must she head the plane?

Answer 1

Consider 100seconds flying. The plane goes 950m. So looking at the vector diagram, sinTheta=2500/950 where theta is the angle S of W. This gives a West resultant.
