#2 For each of the following cases, write down the four components of the 4-momentum in the form [Pt, Px, Py, Pz]. Assume each particle has mass m. (a) A particle moves in the +x direction in the laboratory at speed 0.8. (b) The same particle is observed in the Other Frame, in which it is at rest. (c) Another particle moves in the +z direction in the laboratory with speed 0.7. (d) The particle from part (c) as observed in the Other Frame from part (b). (e) Verify that your particle in part (d) still has mass of m
