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 15 rad/s. At t=
O, the coordinates of G are x₁ = 0 and yo = 2 m, and its velocity is vo= (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.
