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

(A) When an object experiences a net zero external unbalanced force,in accordance with Newton's second law of motion $F = ma$,its acceleration is zero.
If the object was initially in a state of motion,then in accordance with Newton's first law of motion,the object will continue to move in the same direction with the same speed.
It means that the object may be travelling with a non-zero velocity,but the magnitude as well as the direction of the velocity must remain unchanged or constant throughout.
