Unformatted text preview: forces are those that the objects within the system exert on each other. An elastic collision is one in which the total kinetic energy is the same before and after the collision. An inelastic collision is one in which the total kinetic energy is not the same before and after the collision. If the objects stick together after colliding, the collision is said to be completely inelastic. The location x cm of the center of mass of two objects lying on the x axis is given by where m 1 and m 2 are the masses of the objects, and x 1 and x 2 are their positions relative to the coordinate origin. If the objects move with velocities v 1 and v 2 , the velocity v cm of the center of mass is If the total linear momentum of a system of objects remains constant during an interaction such as a collision, the velocity of the center of mass also remains constant....
