1. The origins of two inertial frames coincide at t = 0. The K’ frame moves relative to the K frame at a velocity of 0.92c in the +y direction. A proton is at rest in the K frame. What is the momentum 4-vector of the proton, (E/c, px, py, pz) in the K’ frame (in units of MeV/c)?

Suppose that, at t=6.00×10−4 s, the space coordinates of a particle are x=255 m, y=35.0 m, and z=35.0 m according to coordinate system S. If reference frame S′ moves at speed 1.41×105 m/s in the +x-direction relative to frame S, compute the corresponding coordinate values as measured in frame.S′. The reference frames start together, with their origins coincident at t=0. x' = ??? m y' = ??? m z' = ??? m
