25. A student wants to perform an experiment where they have to measure the time interval for a ball bearing rolling down a slope (as with your first practical), in order to determine the acceleration on the ball-bearing. They take 1 measurement for every distance (they move the end of the measuring equipment 10 cm further way every time), and then they plot a graph. This graph comes out with very scattered values that do not form a straight line at all. What could be the reason for this? Choose all correct answers. A. They should have taken more than one measurement at every distance. B. The stopping wires might have malfunctioned sometimes, so they should have made sure that the stopping wires only touched the metal when the ball bearing rolled over it. C. The graph is fine with only one value measured per distance. It is the acceleration that was not consistent. Nothing needs to be changed. D. The graph axes need to be adjusted to make the data show a straight line.

The graph to the right shows velocity vs. time for a cart on a track with a friction pad attached. The cart was launched from rest by a hoop spring. Use this graph to answer the following question: so long as the ramp is level, even with the friction pad NOT in contact with the track it is impossible to produce a region "b" that is flat (horizontal), i.e. that shows a constant velocity. This is because b V a of errors inherent to the motion detector the acceler tion gravity causes the cart to rate air currents in the room significantly affect the motion of the cart there is still a small amount of friction between the wheels of the cart and the track, and the axels of the cart with the body of the cart achieving constant velocity is not physically realistic under any circumstances
