An unstable atomic nucleus of mass 1.7010-26 kg initially at rest disintegratesinto three particles. One of the particles, of mass 5.07 10-27 kg, moves along the y axiswith a speed of
6.00 106 m/s. Another particle, of mass 8.42 10-27 kg, moves along the x axiswith a speed of 4.00 106 m/s.
(a) Find the velocity of the thirdparticle.
( i hat + j hat) m/s
(b) Find the total kinetic energy increase in the process.
