The Problem:

Find the change in velocity of a yacht if it changes its velocity from

5ms^-1 due north to 3ms^-1 due west and also state its direction.

The solution :

(resultant vel.)^2 = 5^2 + 3^2 = 5.8 ms^-1

direction = tan-1(3/5) = 31 degrees west of north

However , the books answer is 5.8 ms^-1 in a direction 31 degrees west of south . what am i doing wrong here ???
