In a particle accelerator, protons are fired at a stationary target and collide elastically with the nuclei of the atoms in the target. In one such experiment, a beam of protons is fired with a speed of 2.10 × 107 m/s. The protons that undergo a collision rebound with a speed of 1.68 × 107 m/s. What is the mass of the nuclei that the protons are colliding against?
A) 6.00 proton masses
B) 7.00 proton masses
