1. This question is a long free-response question. Show your work for each part of the question. A cylindrical object can roll down an incline, as shown in Figure 1. The incline is slightly less than one meter in length. A group of students wants to determine the acceleration of the object while it is rolling down the incline. The students have access to the following equipment. • A stopwatch, which can measure time intervals up to with a precision of • A clock, which can measure time intervals up to with a precision of • A meterstick, which can measure lengths up to with a precision of • A pair of calipers, which can measure lengths up to with a precision of (a) Assume the object moves with a constant acceleration as it rolls down the incline. Write an equation that includes acceleration and quantities that can be measured or obtained from measurements by using the available equipment in the list. Please respond on separate paper, following directions from your teacher. (b) Design an experimental procedure the students could use to measure the quantities required to determine the acceleration of the object. In the table below, list the quantities and associated symbols that would be measured in your experiment and the equipment used to measure them. Also list the equipment that would be used to measure each quantity. You do not need to fill in every row. If you need additional rows, you may add them to the space just below the table.

Page 2 of 5 Quantity to be Measured Symbol for Quantity Equipment for Measurement Describe the overall procedure to be used, referring to the table. Provide enough detail so that another student could replicate the experiment, including any steps necessary to reduce experimental uncertainty. As needed, use the symbols defined in the table and/or include a simple diagram of the setup. Please respond on separate paper, following directions from your teacher. (c) i. What quantities could be graphed to yield a straight line that could be used to determine the acceleration of the object? Only indicate quantities that either were measured in part (b) or could be determined from quantities measured in part (b). Vertical axis Horizontal axis ii. How cou
