When an object moves in a straight line at a constant speed under the action of F1, F2, F3 and FN, if the force F2 is suddenly removed, how will the object move?

When an object moves in a straight line at a constant speed under the action of F1, F2, F3 and FN, if the force F2 is suddenly removed, how will the object move?

It depends on the relationship between the direction of the original velocity and F2. In the same direction, make a uniform acceleration linear motion. On the contrary, make a uniform deceleration linear motion. The others are parabola
