In a collider two protons are accelerated until they have kineticenergies of 1000 MeV (as seen in the lab). The pair is then splitand brought around circular paths so that they are directed at eachother. What speed of approach would one proton see the other ashaving? The mass of a proton is 1.673x10-27 kg (or 1.007276 u),and the rest mass energy of a proton is 938.3 MeV. (Speed is ascalar, so your answer will not need a direction.)K= 1000 MeVK = 1000 MeV

The kinetic energy of the proton is defined as 1000 MeV. And the rest mass energy be defined as…
