You are at the controls of a particle accelerator, sending beam of 3.90 x 10^7 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 3.60 x 10^7 m/s. Assume that the initial speed of the target nucleus is negligible and that the collision is elastic.(a) Find the mass of one of the nuclei of the unknown element. Express you answer in terms of the proton mass m.(b) What is the speed of the unknown nucleus immediately after such a collision?
Assume the square wire loop is replaced with a smaller one, made of the same wire that is 0.02 m on a side, half as long as the original.
