You are at the controls of a particle accelerator, sending a beam of 2.70×107 protons (mass ) 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 2.40×107. Assume that the initial speed of the target nucleus is negligible and the collision is elastic.
