Worked Solution

Step 1: The force is in the opposite direction of motion. Step [2-9]: This causes the block to decelerate (slow down). Step [2-9]: Once it stops, the constant force will then cause it to accelerate in the direction of the force (left).

Correct answer: The block will slow down, stop, and then move to the left.
