An unstable nucleus of mass 1.7 x 10-26 kg, initially at
rest at the origin of a coordinate system, disintegrates into
three particles. One particle, having a mass of m1 = 5.0 x 10-27 kg, moves in the positive y- direction with speed v 1 =6.0x 106 m/s. Another particle, of mass m2 = 8.4 x 10-27 kg, moves in the positive x - direction with speed v2 = 4.0 x 106 m/s. Find the magnitude and direction of the velocity of the
third particle.
