Chapter 17, Problem 16-21(choose chapter or problem)
16-21. A motor gives disk A a clockwise angular acceleration of aA = (0.6r + 0.75) rad/s2, where / is in seconds. If the initial angular velocity of the disk is co() = 6 rad/s, determine the magnitudes of the velocity and acceleration of block B when / 2 s.
