**Henry**, Wednesday, December 5, 2012 at 7:48pmVp = 185km/h @270o + 68km/h @ 0o.

X = 185*cos270+68*cos(0)=0+68 = 68km/h.

Y = 185*sin270+68*sin(0)=-185+0=-185km/h

tanAr = Y/X = -185/68 = 2.72059.

Ar = -69.82o = Reference angle.

A = -69.82 + 360 = 290o = Direction.

Vp = X/cosA = 68/cos290=197 m/s=Velocity

of plane.
