Solve Prob. 17.111, assuming that the impact is perfectly elastic. Problem 17.111: The 18-lb rigid body BD consists of two identical 2.4-in.-radius spheres and the rod which connects them and has a centroidal radius of gyration of 10 in. The body is at rest on a horizontal frictionless surface when it is struck by the 6-lb sphere A which has a radius of 2.4 in. and is moving as shown with a velocity V1 of magnitude 12 ft/s. Assuming a perfectly plastic impact, determine immediately after the impact,

(a) The angular velocity of body BD,

(b) The velocity of point G.
