Although the IC may be conveniently used to determine the
velocity of any point in a body, it generally does not have zero
acceleration and therefore it should not be used for finding the
accelerations of points in a body.
The velocity of a point on a body which is subjected to general
plane motion can be determined with reference to its instantaneous
center of zero velocity provided the location of the IC is first
established using one of the three methods described above.
