The electron-volt, eV, is a unit of energy (1eV = 1.602 ·10-19 J, 1 MeV = 1.602 ·10-13 J).Since the unit of momentum is an energy unit divided by a velocity unit, nuclear physicists usually specify momenta of nuclei in units of MeV/c, where c is the speed of light (c = 2.998 ·108 m/s). In the same units, the mass of a proton (1.673 ·10-27 kg) is given as 938.3 MeV/c2. If a proton moves with a speed of 13700 km/s, what is its momentum in units of MeV/c?
Two flexible balls rolling along a frictionless horizontal surface collide with each other. The Larger of the balls weighs 50g and the smaller weighs 30g. find the acceleration of the center of mass of the smaller ball
A collision between two protons produces three new particles: p + p --->p + + + 0 + 0. The rest energies of the new particles are + (139.6 MeV), 0 (1116 MeV), 0 (497.7 MeV). Note that one proton disappears during the reaction. How much of the protons..
