Answer: F
Explanation: 8N is greater than 6N. Therefore, the car will accelerate to the right.
In Answer G, the forces to the left are greater than the forces on the right. The car will move, but it will decelerate.
In Answer H, both forces are equal, so the car will not move.
In Answer I, the forces to the left are greater than the right. The car will move, but it will also decelerate, as seen in Answer G.
In Answer F, the forces to the right are greater than the forces on the left. The car will accelerate to the right.
