A woman sits in a rigid position on her rocking chair by keeping her feet on the bottom rung at B. At the instant shown, she has reached an extreme backward position and has zero angular velocity. Determine her forward angular acceleration a and the frictional force at A necessary to prevent the rocker from slipping. The woman and the rocker have a combined mass of 90 kg and a radius of gyration about G of kg = 0.45 m. 0.2 m 0.48 m
