If the mass of the hanging-mass is increased and the mass of the cart remains the same, how would the steepness of the position versus t2 be affected? The best-fit line would decrease in steepness.The best-fit line would increase in steepness. Impossible to determine because the net force is not a part of the position vs t2 graph.There would be no change in steepness.
