(2) In a real experiment with the setup of Figure 2, initially the disk is at rest, and the hanging mass is placed 0.500 m above the floor. Then the hanging mass falls down until finally touches the floor. Measurements show the hanging mass my = 0.115 kg, the spindle radius r = 0.0251m, the disk's angular acclerating = 3.551 rad/s , and the disk's final angular velocity wf = 11.29 rad/s. Please compute the quantities below to 3 sig. figs.: (hint: properly use Eqs. (1) - (10) . Take g = 9.80 m/s'.) 1. Hanging mass's acceleration a 6. Hanging mass's final velocity Uh (from 2.
