Question 3 (12 points) A solid disk of unknown mass and known radius R is used as a pulley in a lab experiment, as shown in the diagram. Students want to determine the moment of inertia of the pulley. They attach a small block of mass m to a string, the other end of which is attached to the pulley and wrapped around it several times. The block of mass m is released from rest and takes a time / to fall the distance D to the floor. (a) The time / is measured for various heights D, and the data are recorded in the following table. D (m) 1 (s) O.5 0.68 1.02 1.5 1.19 2 1.38 (i) What quantities should be graphed to best determine the acceleration of the block? Explain your reasoning. AP* Physics 1: Rotation and Angular Momentum (ii) On the grid provided, plot the quantities determined in Part (a)(i), label the graph and axes, and draw the best-fit line to the data. (iii) Use your graph from Part (a)(ii) to calculate the magnitude of the acceleration
