. An object experiences a net zero external unbalanced force. Is
it possible for the object to be travelling 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.

Yes, an object may travel with a non-zero velocity even when the net external force on it is zero. A rain drop falls down with a constant velocity. The weight of the drop is balanced by the up thrust and the velocity of air. The net force on the drop is zero. When a net zero external unbalanced force is applied on the body, it is possible for the object to be travelling with a non-zero velocity. In fact, once an object comes into motion and there is a condition in which its motion is unopposed by any external force; the object will continue to remain in motion.Yes, an object can have zero velocity and still be accelerating simultaneously. ... When the object stops for a moment, its velocity at that instant is zero, therefore no motion in either forward or backward direction. However the acceleration is still acting on it.
