PLEEEASE HELLPPP!!!! 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?
(1 point)
O acceleration
O velocity
O mass
O force
