A. Some of the kinetic energy of trolley X is changed to momentum in the collision
B. Some of the momentum of trolley X is changed to kinetic energy in the collision
C. Trolley X loses some of its momentum as heat in the collision
D. Trolley X shares its momentum with trolley Y but some of its kinetic energy is lost
