You are at the controls of a particle accelerator, sending a beam of 3.60×107 m/s protons (mass m) at a gas target of an unknown element. your detector tells you that some protons bounce straight back after a collision with one of the nuclei of the unknown element. all such protons rebound with a speed of 3.30×107 m/s. assume that the initial speed of the target nucleus is negligible and the collision is elastic. what is the speed of the unknown nucleus immediately after such a collision?
