1. The problem statement, all variables and given/known data A particle of rest mass m0 collides elastically with a stationary particle of equal mass and scatters at angle θ. The incident particle has kinetic energy T0 before the collision and T1 after the collision. (a) Show that T12 (2m0c 2 + T0) 2 = p02 p12 c4 cos2 θ. (b) Using the results of part (a) and problem 6, find T1 as a function of θ. 2. Relevant equations 3. The attempt at a solution p0+p1=p0'+p1'
