Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force applied to the object. We concluded from the data obtained during the experiment that the law:
A) is valid because as the force F increased, the acceleration of the cart decreased.
B) is valid because as the force F increased, the acceleration of the cart increased.
C) is valid because as the force F decreased, the acceleration of the cart increased.
D) is not valid.
3. In the Newton's 2nd Law experiment, a group of students using a cart and an additional 0.86 kg of mass acquired data to plot an F vs. acceleration graph. From this graph, it was determined that the slope was 1.44 and the y-intercept was 0.06. They were then asked to analytically determine the mass of the cart. What would be their answer?
A) 1.44 kg
B) 0.86 kg
C) 0.58 kg
D) 0.06 kg
