Aball of mass m traveling at a speed of 0.80c has a perfectly inelastic collision with an identical ball at rest. if newtonianphysics were correct for these speeds, momentum conservation would tell us that a ball of mass 2m departs the collisionwith a speed of 0.40c. let’s do a relativistic collision analysis to determine the mass and speed of the ball after thecollision. a. what is 7", written as a fraction like a/b? b. what is the initial total momentum? give your answer as a fraction times mc. c. what is the initial total energy? give your answer as a fraction times m2. don't forget that there are two balls. d. because energy can be transformed into mass, and vice versa, you cannot assume that the final mass is 2m. instead, letthe ﬁnal state of the system be an unknown mass m traveling at the unknown speed uf. you have two conservation laws. find m and uf.
