Placing additional discs on the car mistakenly increases its mass, which would lead to a decrease in acceleration according to Newton's second law (F = ma), assuming the applied force remains constant. As a result, the car would accelerate more slowly than in the previous trials where only the force from the hanger acted on it.
Students are using the experimental setup shown in the image in which the two ends of a string are attached to a car and to a
hanger. The students conduct three trials 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
would this change the acceleration or velocity?
