3. Examine the mt graph for Run 2. Determine the rate of change of mbefore you dropped the second disk onto the first Record the angular velocity just before and just after you increased the mass of the system. Determine the time interval (at) between these two velocity readings. :- in Logger Pro, drag-select the interval between these two readings. The x in the lower left corner gives the value of At. .- In LabQuest App, drag and select the interval between these two readings and use the Delta function under Statistics to perform this task. 4. The angular momentum, L, of a system undergoing rotation is the product of its moment of inertia, l , and the angular velocity, at Lzlm Determine the angular momentum of the system before and after you dropped the second aluminum disk onto the first Calculate the percent difference between these values
