Three identical hockey pucks are located on a horizontal frictionless surface as shown above. B and C are initially at rest, and A has initial belocity 12 ft/s to the right, as shown. Given that A hits B, and then C, that A has velocity 6 ft/s to the right after both impacts, and that B's and C's final velocitoes both subtend the same angle with the horizontal (X-direction), use conservatin of Linear Momentum and Conservation fo Total Energy to find:

a) V_b and V_c

b) theta
