Solve the below problem:
Q: A 17.5-lb sphere A of radius 4.5 in. moving with a velocity v0 of magnitude v0 = 6 ft/s strikes a 1.6-lb sphere B of radius 2 in. which was at rest. Both spheres are hanging from identical light flexible cords. Knowing that the coefficient of restitution is 0.8, determine the velocity of each sphere immediately afterimpact.
