An inelastic cord is anchored at point B at the top of a 20 degree slope as the cord is unwound from a spool rolling downhill under the influence of its own weight. The mass of the spool is 200 kg, with inner hub radius R, = 0.4 m and an outer flange radius of R, = 0.6 m. The radius of gyration of the spool about its mass center is ko = 0.27 m. The coefficient of kinetic friction between the slope and the spool rim is , = 0.2. The cord does not slip on the spool. Find the mass center's velocity 10 s after the spool has been B DRAR released from rest. (Answer: 16.7 m/s down the incline)
