In the experimental setup shown, a car has one end of a string attached to it, and the other end is attached to a fixed number of metal discs. The car moves along the table and two probes sense the motion of the car. The probes send information to a computer that displays the acceleration and velocity of the experiment. When looking at these results, which quantity stays constant during the trials?

In the experimental setup you described, the quantity that stays constant during the trials is mass.
The mass of the car and the attached discs does not change throughout the trials, whereas force, acceleration, and velocity can vary depending on the interactions and conditions of the experiment.
