Two rigid bodies collide. We can solve for the post-impact velocities of the centers of mass of the bodies if we know (select all that are true):
A. Masses of the bodies and incoming velocities of their centers of mass.
B. Masses of the bodies and incoming velocities of their centers of mass plus post impact velocity of the center of mass of one body.
C. Masses of the bodies and incoming velocities of their centers of mass plus post impact directions of the centers of mass of the bodies.
D. Masses of the bodies and incoming velocities of their centers of mass plus post impact speeds of the centers of mass of the bodies
E. None of the above, further information is required.
