Question
As two boats approach the marina, the velocity of boat 1 relative to boat 2 is 2.20m/s in a direction 47.0 ∘ east of north.
If boat 1 has a velocity that is 0.745m/s due north, what is the velocity (magnitude and direction) of boat 2?

Boat 1 north velocity as seen from boat 2 = boat 1 north speed - boat 2 north speed
2.2 cos 47 = .745 - boat 2 north
Boat 1 east as seen from boat 2 = boat 1 east - boat 2 east
2.2 sin 47 = 0 - boat 2 east
2.2 cos 47 = .745 - boat 2 north
Boat 1 east as seen from boat 2 = boat 1 east - boat 2 east
2.2 sin 47 = 0 - boat 2 east
