Two protons (each with mass mp = 1.67 x 10-27 kg) are initially moving with equal speeds in opposite directions. They continue to exist after a head-on collision that also produces a neutral pion of mass mp = 2.40 x 10-28 kg (Fig.). If all three particles are at rest after the collision, find the initial speed of the protons. Energy is conserved in the collision.
