A 0. 50 kg ball traveling at 6. 0 m/s due east collides head on with a 1. 00 kg ball traveling in the opposite direction at -12. 0 m/s. After the collision, the 0. 50 kg ball moves away at -14. 0 m/s. Find the velocity of the second ball after the collision.

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
