Solution:
where V_{pg }= 1000 km / 2.5 hr at 45^{0 }North of East
V_{pg }= 400 km/hr 45^{0 }North of East
V_{wg }= 75 km/hr at 70^{0 }South of East
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, V_{wg}.
This satisfies the vector equation and ensures the addition of the vectors
in the tiptotail convention.
