Fig. A-16(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 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.
