An airplane is traveling 775 km/h in a direction 42.5° west of north (Figure 3-31).

Question

(a) Find the components of the velocity vector in the northerly and westerly directions.

northerly km/h
westerly km/h

(b) How far north and how far west has the plane traveled after 3.00 h?

north km
west km

Answer 1

N: 775 cos 42.5°
W: 775 sin 42.5°

now recall that distance = speed * time
