The amount of net force keeping the object moving at this constant speed and in this direction is zero (0) newton.
Newton's First Law of Motion is also referred to as Law of Inertia and it states that an object in motion would continue in its state of motion at continuous velocity (same speed and direction) or if at rest, it will remain at rest unless it is acted upon by an external force.
This ultimately implies that, the amount of net force keeping the object moving at this constant speed and in this direction is equal to zero (0) newton in accordance with Newton's First Law of Motion.
