Two 2.6-lb collars A and B can slide without friction on a frame, consisting of the horizontal rod OE and the vertical rod CD, which is free to rotate about CD. The two collars are connected by a cord running over a pulley that is attached to the frame at O and a stop prevents collar B from moving. The frame is rotating at the rate = 10 rad/s and r = 0.6 ft when the slop is removed allowing collar A to move out along rod OE. Neglecting friction and the mass of the frame, determine (a) the tension in the cord and the acceleration of collar A relative to rod OE immediately after the stop is removed, (b) the transverse component of the velocity of collar A when r= 0.9 ft.
