Physics 12 - Quiz #5
North to Alaska!

Solution:

a) The vector equation for the velocity of the plane with respect to the wind is given by,
 

Vpw = Vpg + Vgw

b) We can now draw the vector diagram the represents the vector equation. Note the reversal of the velocity vector, wind w.r.t. ground, Vwg.  This satisfies the vector equation and ensures the addition of the vectors in the tip-to-tail convention.
 

 

The heading is thus given by 6.80 + 240 = 30.80 West of North
