An object experiences a net zero external unbalanced froce.Is it possible for the object to be travelling with non-zero velocity?If yes,state the conditions that must be placed on magnitude and direction of velocity.If no,provide a reson.

Yes it can, and there are no conditions. A gimmick: you can always make the velocity appear to be whatever you please, by simply choosing an appropriate reference frame. And that is why there are no conditions.

If the net external force is zero then the body will continue in its state of rest or uniform motion ie velocity can be non-zero while travelling with a particular magnitude and a particular diretion at that instant of time.

Force is one which changes the velocity. If there is no net force then there is nothing to change its velocity. Therfore it continues to move with the same velocity when there is no net force.
Thus any object will move with the same velocity when there is no net force ( Newtons first law)
In a special case when the velocity is zero and the net force is also zero the objcct moves with zero speed; that is, it is at rest.

If there is no net force the object must have zero velocity. This is because the forces of friction will cause the object to slow down.

it is possible i guess if u place a glass piece on a frictionless surface it will move in an absolutely straight line with non-zero velocity but the velocity remains constant and does not change. coz objecs move in a straight line without frction. and to change the constant velocity while the object is moving u need to put an unbalanced external force. thats it
bye

net zero force means that is state remains the same always. thus either it is still , at rest, does not move at all, or it moves WITH A CONSTANT VELOCITY. the magnitude does nto change nor its direction fullfilling all prerequisits.
so it either remains at rest --- or it moves with constant velocity

frame of reference is the main cause
