Question

An airplane heading northwest at 500km/h encounters a wind of 120km/h from 25deg north of east. Determine the resultant ground velocity of the plane

Answer 1

135 degres at 500km\h
and 25 degres at 120km\h
-use law of cos
between both:135-25=110
resultant:r
r^2=150^3+120^2-(2*500*120*cos110)
r^2=305442.4172
r=552.67

Answer 2

552.67km\h, if you draw a triangal, you can calculate the orientation

Answer 3

where u get 135 deg from?
