Question 1

When a stationary plutonium-239, Pu, decays into uranium-235 plus an alpha particle, the energy released in the process is 5.24 MeV. The following masses are known:
He:4.002603 u
U:235.043924 u
What is the mass of the Pu nucleus, in amu? (1 u = 931.494 MeV/c2)
◦ 238.98884 u
◦ 239.00189 u
◦ 239.02775 u
◦ 239.05215 u
◦ 238.99919 u

Question 2

When a stationary plutonium-239 nucleus decays into a uranium-235 nucleus plus an alpha particle, the energy released in the process is 5.24 MeV. The following masses are known:
He:4.002603 u
U:235.043924 u
What is the kinetic energy of the U nucleus? (1 u = 931.5 MeV/c2)
◦ 0.0877 MeV
◦ 0.0837 MeV
◦ 0.0852 MeV
◦ 0.0829 MeV
◦ 0.0863 MeV
