You are at the controls of a particle accelerator sending a beam of 1.50 x 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 1.2 x 10' m/s. Assume that the initial speed of the target nucleus is negligible and the collision is elastic. A. Find the mass of one nucleus of the unknown element in terms of the proton mass m. B. What is the speed of the unknown nucleus immediately after such a collision? C. Show that the total kinetic energy is the same before and after the collision.

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
