NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Two small disks A and B of mass 2 kg and 1 kg, respectively, may slide on a horizontal and frictionless surface. They are connected by a cord of negligible mass and spin about their mass center G. At t = 0, G is moving with the velocity v0¯¯¯ and its coordinates are x0¯¯¯= 0 and y0¯¯¯= 1.89 m. Shortly thereafter, the cord breaks and disk A is observed to move with a velocity vA= (5 m /s)j in a straight line and at a distance a = 2.56 m from the y axis, while B moves with a velocity vB= (7.2 m/s)i - (4.6 m/s)j along a path intersecting the x axis at a distance b =7.48 m from the origin O
