An unstable atomic nucleus of mass 1.84 x 104 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.10 x 10 kg., moves in the y direction with a speed of 6.00 x 10° m/s. Another particle, of mass 8.44 x 10 kg. moves in the x direction with a speed of 4.00 x 10° m/s. (a) Find the velocity of the third particle. i) m/s (b) Find the total kinetic energy increase in the process.
