Question

Wind is blowing NE with 18✓2 km/h and steamer is heading due west with 18km/h. In which direction is the flag on the mast futtering ?​

Answer 1

For this question you have to find resultant velocity. Let Vw be velocity if wind and Vs be velocity of steamer. If you plot them using four quadrants you will find that angle between them is 135°.

Let angle at which flag flitters is alpha.

Then
