An airplane is heading due south at a speed of 515 km/h. A wind begins blowing from the southwest at a speed of 100 km/h (average). (Hint: First draw a diagram.)

Question

(a) What is the velocity (magnitude and direction) of the plane relative to the ground? magnitude/direction (east of south)
(b) How far off course will it be after 8 min if the pilot takes no corrective action?

Answer 1

225

Answer 2

a,515km/h-100km/h=415km/h
i.e (415km/h*1000m)/1h(60*60)s=115m/s

Answer 3

8km
