Part B What would the speed be if it were computed from the principles of classical mechanics? Express your answer in meters per second.
- that the axes get closer to one another. 2. Prove that the "interval", defined as x² +v² + =² – c²¢ is a conserved quantity across reference frame transformations. 3. Consider two events. Give an example of coordinates x,y,z,t and x',y',z',t and relative2A ball of mass m traveling at a speed of 0.80c has a perfectly inelastic collision with an identical ball at rest. If Newtonian physics were correct for these speeds, momentum conservation would tell us that a ball of mass 2m departs the collision with a speed of 0.40c. Let's do a relativistic collision analysis to determine the mass and speed of the ball after the collision. Part C What is the initial total energy? Give your answer as a fraction times mc². Don't forget that there are two balls. Express your answer in terms of c and m. IVD ΑΣΦ E= Submit Part D Uf = Request Answer Because energy can be transformed into mass, and vice versa, you cannot assume that the final mass is 2m. Instead, let the final state of the system be an unknown mass M traveling at the unknown speed uf. You have two conservation laws. Find uf. Express your answer in terms of c and m. Submit IVE ΑΣΦ ?
