One of the waste products of a nuclear reactor is plutonium-239 (239pu). This nucleus is radioactive and decays by splitting into a helium-4 nucleus and a uranium- 235 nucleus (239 Pu → He +235 U), the latter of which is also radioactive and will itself decay some time later. The energy emitted in the plutonium decay is 8.40x10-13 J and is entirely converted to kinetic energy of the helium and uranium nuclei. The mass of the helium nucleus is 6.68x10-27 kg, while that of the uranium is 3.91x10-25 kg (note that the ratio of the masses is 4 to 235). Calculate the velocity of the helium nucleus, assuming the plutonium nucleus is originally at rest. Submit Answer Tries 0/40 Calculate the velocity of the uranium nucleus. Submit Answer Tries 0/40 How much kinetic energy does the helium nucleus carry away? (Note that the data given here are accurate to three digits only.)

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
