Biomaterials made with nanotechnology are currently used for organ repair, skin transplants, and cell growth. organ repair, quantum dots, and carriers. quantum dots, oleds, and carriers. cell growth, oleds, and skin transplants.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
