1. In nonrelativistic physics, the center of MASS of an isolated system moves with constant velocity. (This is also a statement of conservation of linear momentum.) In relativistic physics, the center of ENERGY moves with constant velocity. Consider a system of two particles. Particle A of mass 9m has its position given by xa(t)=(4/5)ct, while particle B of mass Sm is at rest at the origin, before they collide at time t=0. The two particles stick together after the collision. II Use relativistic physics to solve the problem of the system of two colliding particles. a) What is the position of the center of energy of the system before the collision? b) What is the velocity of the center of energy of the system before the collision? c) What is the mass (rest mass) of the final composite particle? d) What is the velocity of the final composite particle? e) What is the position xc(t) of the final particle after the collision? f) Compare the energy and momentum of the system before and after the collision.
