No, it’s not. “North” is a two dimensional direction on the surface of the earth. But we live, and can throw babies, in three dimension. Therefore you need to specify the inclination as well. “56 furlongs per minute, north, 0.3 radians” would suffice.
Velocity is speed and direction. So “16.4 mph north” is sufficient.

It is not. It’s not in metric.
