An atomic nucleus at rest at the origin of an xy coordinate system transforms into three particles. Particle 1, mass 1.67 x 10^-26 kg, moves away from the origin at velocity (6.00 x 10^6 m/s)ihat ; particle 2, mass 8.35 X 10^-27 kg, moves away at velocity (-8.00 x 10^6 m/s)jhat.
(a) In unit-vector notation, what is the linear momentum of the third particle, mass 1.17 x 10^-26 kg?
kg · m/s ihat+ kg · m/s jhat

(b) How much kinetic energy appears in this transformation?
J
