Consider an airplane that normally has an air speed of 120 km/h in a 105 km/h crosswind blowing from west to east. Calculate its ground velocity when its nose is pointed north in the crosswind?

Answer 1

Add the two perpendicular velocity vectors

V = sqrt[(105)^2 + (120)^2] = 159.5 km/h (ground speed magnitude)

The direction is arctan(105/120) = 41.2 degrees E of N

Answer 2

PLane flying at 220 mph heading north with 20 mph crosswind . What is the heading angle you should take,AND WHAT IS ITS RELATIVE GROUND SPEED.
