It will move at a constant speed to the left.

It will move at an increasing speed to the left.
It will move at an increasing speed to the left.

It will move at an increasing speed to the right.
It will move at an increasing speed to the right.

It will move at a constant speed to the right.

Answer 1

I don't see the picture — could you upload it or describe the two forces (their directions and magnitudes)?

Meanwhile, here’s how to decide:
- Add the two force vectors to get the net force.
- On a frictionless surface the box accelerates in the direction of the net force (a = Fnet/m).
- If Fnet = 0 the box stays at rest (constant speed = 0).
- If Fnet points left, the box will speed up (increasing speed) to the left; if Fnet points right, it will speed up to the right.

Give the force magnitudes and directions (or re-upload the image) and I’ll pick the correct choice.
