A spool of thin wire (with inner radius r = 0.40 m, outer radius R = 0.55 m, and moment of inertia Icm = 0.71 kg*m2 pivots on a shaft. The wire is pulled down by a mass M = 1.40 kg. After falling a distance D = 0.52 m, starting from rest, the mass has a speed of v = 75.400 cm/s. Calculate the energy lost to friction during that time.
