Two balls of equal mass collide and stick together as shown in the figure. The initial velocity of ball B is twice that of ball A.

a) Calculate the angle above the horizontal of the motion of mass A + B after the collision.

b) What is the ratio of the final velocity of the mass A + B to the initial velocity of ball A, vf/vA?

c) What is the ratio of the final energy of the system to the initial energy of the system, Ef /Ei? Is the collision elastic or inelastic?
