238 kg kg, A uranium nucleus U may stay in one piece for billions of years, but sooner or later it de- cays into an a particle of mass 6.64 x 107 and 234Th nucleus of mass 3.88 x 107 and the decay process itself is extremely fast (it takes about 10-20 s). Suppose the uranium nucleus was at rest just before the decay. If the a particle is emitted at a speed of 6.67 x 106 m/s, what would be the recoil speed of the thorium nucleus? Answer in units of m/s.
