Question

a aircraft is flying to north with velocity of 350 m/s, aside wind of velocity 100m/s is blowing due to west.
what is the resultant velocity ?
what is the direction of resultant velocity?
how far this aircraft travels during 1 hour?

Answer 1

X = Vw = -100 m/s.
Y = Vp = 350 m/s.
Q2.

Vr = Sqrt(X^2 + Y^2).

Tan A = Y/X = 350/-100 = -3.500.
A = -74o = 74o N. of W. = 16o W. of N. =
Direction.

d = Vr * 3600s = Meters.

Note: 3600 s = 1 hour.
