V PartA Two protons (each with rest mass M = 1.67 X 10'27 kg) are initially moving with equal speeds in opposite directions. The protons continue to exist after a collision that also produces an n0 particle. The rest mass of the n0 is Express your answer as a multiple of the speed of light. m = 9.75 x 10*28 kg. It the two protons and the n0 are all at rest after the collision, find the initial speed of the protons, expressed as a fraction of the speed of light. .Azcbmo?
