Two protons (resting mass M=1.67*10-27kg) move in opposite directions at the same rate. After collision, the protons are retained, but the collision results in a new particle having a rest mass of m=2.75*10-28kg.

1a) Calculate the kinetic energy of the proton in MeV

An object of mass M moving at speed v0 has a direct elastic collision with a second object of mass m that is at rest. Using the energy and momentum conservation principles, it can be shown that the final velocity of the object of mass M is v=(M−m)v0/(M+m). Part A Using this result, determine the final velocity of an alpha particle following a head-on collision with an electron at rest. The alpha particle's velocity before the collision is 0.010c; malpha=6.6×10−27kg;...
