The jet transport B is flying north with a velocity vB = 640 km/h when a smaller aircraft A passes underneath the transport headed in the 69 direction shown. To passengers in B, however, A appears to be flying sideways and moving east. Determine the magnitudes of the actual velocity of A and the velocity which A appears to have relative to B.

The jet transport B is flying north with a velocity VB = 640 km/h when a smaller aircraft A passes underneath the transport headed in
the 69° direction shown. To passengers in B, however, A appears to be flying sideways and moving east. Determine the magnitudes
of the actual velocity of A and the velocity which A appears to have relative to B.
