The velocities along the A and B axes are such that the direction of motion follows the specified path,
yet the vector velocity fits the vector speed and acceleration requirements.

Fig. A-12(a) shows the vector velocity. It also indicates the position point along the path starting at A
and ending at D. Between the points A and B, the motion is along the B axis. Therefore,
