Which one of the following situations is not possible? a body has zero velocity and non-zero acceleration. a body travels with a northward velocity and a southward acceleration. a body travels with a northward velocity and a northward acceleration. a body travels with a constant velocity and a constant non-zero acceleration. a body travels with a constant acceleration and a time-varying velocity.

Explanation:

A body has zero velocity and non- zero acceleration. It is possible as at the time when a body thrown upwards is at the top of the height. In that case velocity is zero but acceleration is equal to g.

A body travels with northward velocity but southward acceleration . it is also possible as in case when a body is going with northward velocity  but when break is applied acceleration becomes  southward.

A body travels with northward velocity and northward  acceleration . it is also possible as in case when a body is going with northward velocity  and  when accelerator  is applied . Acceleration becomes northward.

A body travels with constant velocity and a constant non zero acceleration . It is not possible . When there is acceleration , there must be a a change in velocity either in terms of magnitude or direction or both.

A body travels with a constant acceleration and a time varying velocity. It is possible. Time varying velocity represents acceleration.
