Three small identical spheres A, B, and C, which can slide on a horizontal, frictionless surface, are attached to three strings of length l which are tied to a ring G. Initially the spheres rotate about the ring which moves along the x axis with a velocity v0. Suddenly the ring breaks and the three spheres move freely in the xy plane. Knowing that vA = (2.6 m/s)j, vC = (4.5 m/s)i, a = 260 mm, and d = 150 mm, determine(a) The initial velocity of the ring,(b) The length l of the strings,(c) The rate in rad/s at which the spheres were rotating aboutG.
