Expert Answer:
Yes, a body can may posses zero velocity but finite acceleration.
IN FOLLOWING CONDITIONS VELOCITY IS ZERO BUT ACCELERATION IS NOT
1) At the topmost point when body is thrown vertically upwards
2) At the exterme positions of body under SHM (case of spring as well as that of pendulum)
3) A ball thrown upwards on inclined surface, and at the topmost point when it reverses its velocity is zero but acceleration is not (the acceleration is component of g along inclined plane that is g sin@ where @ is inclination of the plane with horizontal)
All these are ofcourse instataneous
