A 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.

Transcribed Image Text:A 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.
