A velocity of magnitude 30m/s

Question

is directed at an angel at an angel of 40° east of north.draw a vector to represent this velocity

Answer 1

WelI suppose you mean on an x y axis system, not a nautical chart.
If so then 30 sin 40 on the x axis and 30 cos 40 on the y axis
30 sin 40 = 30 * .643
30 cos 40 = 30 * .766
