The smaller disk dropped onto a larger rotating one. (frame rate=30fps. Frames=36)(time 1.2 s). The large disk is made of dense plywood rotating on a low-friction bearing. The masses of the disks are:large disk: 2.85kgRadius of large disk= 60cmsmall disk: 3.06 kgRadius of small disk= 36 cmShow how you use measurements and calculations to predict the final angular speed of the two-disk system. The exact same collisions as the previous section, but now you can make measurements of the motion after the two disks are moving together. (frames=124. Time=4.133s. Frame rate=30 fps)calculations to determine the final speed of the two disk rotating together, and calculate the percent difference between your predicted value and the measured value. The final velocity of the two-disk system should be measured when the two disks reach the same angular velocity. How can you tell when that happens?Determine the total angular momentum of the two-disk system after the smaller disk is dropped on the larger one. Calculate the percent difference:Compare the percent change in angular momentum of the system to the percent change in the rotational kinetic energy of the system. Explain the difference between these two values.
