An unstable atomic nucleus of mass 1.76 x 10-26 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.19 x 10-27 kg, moves along the y axis with a speed of 6.00 x 106 m/s. Another particle, of mass 8.50 x 10-27 kg, moves along the x axis with a speed of 4.00 x 106 m/s. You can solve for the velocity of the third particle. Find the total kinetic energy increase in the process.
