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 clockwise 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 = (3.5 ft/s)j, vC = (6.0 ft/s)i, a =16 in. and d = 9 in., 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 about G.
