north wind due to boat speed at 16 kn
west wind at 10.4 kn
magnitude = sqrt(16^2+10.4^2)
tan angle west of north = 10.4/16
compass angle= 360 - that angle
A sailboat is heading directly north at a speed of 16 knots (1 knot = 0.514 m/s). The wind is blowing towards the east with a speed of 10.4 knots. (Both velocities are given relative to the Earth.)
Determine the magnitude and direction of the wind velocity as measured on the boat.
