Q. A spool of thin wire (with inner radius r = 0.50 m, outer radius R = 0.65 m, and moment of inertia I_cm = 1.1323 kg*m2) pivots on a shaft. The wire is pulled down by the mass M = 1.450 kg. After falling a distance D = 0.560 m, starting from rest, the mass has a speed of v = 73.8 cm/s. Determine the energy lost to friction throughout that time.
