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

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
