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.

Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.

3. Your engineering firm has been asked to determine the deceleration of a car during hard braking. To do so, you decide to measure the lengths of the skid marks when stopping from various initial speeds. Your data are as follows: Skid length (m) Speed (m/s) 10 7 15 14 20 27 25 37 30 58 a. Do the data support an assertion that the deceleration is constant, independent of speed? Explain? b. Determine an experimental value for the car's deceleration- that is, the absolute value of the acceleration Your analysis method should involve fitting a straight line to an appropriate graph.
