Aneutron is an electrically neutral subatomic particle with a mass just slightly greater than that of a proton. a free neutron is radioactive and decays after a few minutes into other subatomic particles. in one experiment, a neutron at rest was observed to decay into a proton (mass 1.67×10^−27kg) and an electron (mass 9.11×10−31kg). the proton and electron were shot out back-to-back. the proton speed was measured to be 1.0×105 m/s and the electron speed was 3.2×107 m/s . no other decay products were detected. a. did momentum appear to be conserved in the decay of this neutron? b. if a neutrino was emitted in the above neutron decay, in which direction did it travel? c. explain your reasoning. d. how much momentum did this neutrino carry away with it?
