A uranium nucleus 238U may stay in one place for billions of years, but sooner or later it decays into an x particle of mass 6.64e-27kg and 237Th nucleus of mass 3.88e-25kg, and the decay process itself is extreamly fast (it takes about 10^-20s). Suppose the uranium nucleus was at rest just before the decay. In the x particle is emitted at a speed of 1.23e7 m/s, what would be the recoil speed of the thorium nucleus? answer in units of m/s
