Question
A certain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino.
The parent was at rest at the origin of an xy coordinate system. The electron moves away from the origin with linear
momentum (-7.8 × 10-22 kg m/s) î; the neutrino moves away from the origin with linear momentum (-2.8 × 10-23 kg m/s) j.
What are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) If the
daughter nucleus has a mass of 5.6 × 10-26 kg, what is its kinetic energy?
