Question:
Two small disks, A and B, weighing 4.8 lb and 2.4 lb, respectively, can slide on a horizontal, frictionless surface. They are connected by a cord, 3 ft long, and spin counterclockwise about their mass center G at a rate of 8 rad/s. At t = 0, the coordinates of G are x0 = 0, y0 = 7.44 ft, and its velocity is v0 = (5.76 ft/s)i + (1.44 ft/s)j. Shortly thereafter the cord breaks; disk A is then observed to move along a path parallel to the y axis and disk B along a path which intersects the x axis at a distance b = 24 ft from O. Determine
(a) The velocities of A and B after the cord breaks,
(b) The distance a from the y axis to the path ofA.
