part 1 of 2
A particle of mass m traveling at velocity Vo makes a glancing collision with a particle of the same mass initially at rest. After the collision,the struck particle recoils at 35 to the original line of motion, while the incoming particle moves off at 55 to the original line of motion. No external force acts during the collision.
