The velocities along the X and Y axes are such that the direction of motion follows the specified path, yet the vector 
velocity fits the vector speed and acceleration requirements. 
For example, the velocities along the X and Y axes for the path shown in Fig. A.13 are given in Fig. A.15. 
Fig. A.15a 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 Y axis.  Therefore, 
Vy = Vs 
and 
Vx = 0 
Between the points B and C, the velocities vary gradually and finally, between the points C and D, the motion is in 
the X direction.
