Students are using the experimental setup in which two ends of a string are attached to a car and to a hanger. The students conduct three trails in which they place metal discs on the hanger to manipulate the force applied to the car. As a result the car accelerates along the table while two probes collect motion data. On the fourth trial of this experiment, a student places some discs on the car by mistake. In 1-2 sentences, explain how this mistake will affect the graphs produced by the computer.
