An airplane has a velocity 325km/h relative to the air. It is going in a direction [S30W]. There is a wind velocity of 80km/h[W]. What is the velocity of the plane relative to the ground?
aVg + pVa = pVg
(velocity of air relative to ground + velocity of plane relative to air = velocity of plane relative to ground)
The Attempt at a Solution
pVa = 325km/h
i know pVg^2 = aVg^2 + pVa^2
but, i'm not getting the number i'm supposed to?
