Question 6 of 9 < > -/1 E 1 View Policies Current Attempt in Progress Disk B weighs 43 lb and has a centroidal radius of gyration of 11 in. The power unit C consists of a motor M and a disk A, which is driven at a constant angular speed of 1620 rev/min. The coefficients of static and kinetic friction between the two disks are μ,-0.61 and p 0.46, respectively. Disk B is initially stationary when contact with disk A is established by application of the constant force P-3.6 lb. Determine the angular acceleration a of B and the time t required for B to reach its steady-state speed. The angular acceleration is positive if counterclockwise, negative if clockwise. 30* TA 12.8 in. 7-14.5 in.
