Two small disks A and B, of mass 3 kg and 1.5 kg, respectively, may slide on

Question:

Two small disks A and B, of mass 3 kg and 1.5 kg, respectively, may slide on a horizontal, frictionless surface. They are connected by a cord, 600 mm, long, and spin counterclockwise about their mass center G at the rate of 10 rad/s. At t = 0, the coordinates of G are xÌ…0 = 0, yÌ…0 = 2 m, and its velocity is vÌ…0 = (1.2 m/s)i + (0.96 m/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 = 7.5 m 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 of A.
