An unstable atomic nucleus of mass 1.60 x 10-26 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.18 x 10-27 kg, moves in the y direction with a speed of 6.00 106m/s. Another particle, of mass 8.44 x 10-27 kg, moves in the x direction with a speed of 4.00 x 106m/s. Find the Velocit of partical 3, and find the total kinetic energy increase in the process.
