A body has zero velocity and finite acceleration.Is this possible.Answer with example.

Yes, a body can have zero velocity but finite acceleration.

For example:

1) At the topmost point when body is thrown vertically upwards

2) At the extreme 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 sinx where x is inclination of the plane with horizontal)

All these are of course instantaneous.
