Joseph, Winston, and Franklin are doing an experiment in lab that involves rotational dynamics. Using the apparatus below, Joseph places a disk with a mass of 379 g on the apparatus. Winston then hangs a 15 g mass from the pulley and releases it. The 15 g mass drops and then rises back up, then drops again. ring er d They each graph the angular acceleration a as a function of time as the hanging weight drops and rises. Their graphs are shown below. Only one is correct. Identify the correct graph and explain why it is correct. (10 pts). For the incorrect graphs, explain why they are not correct. (two explanations at 10 pts each = 20 pts for this portion; 30 pts total.) %3D Joseph, Winston, and Franklin are doing an experiment in lab that involves rotational dynamics.
