In K the velocities at time t and t + dt are respectively v and v + wdt along x - axis which is parallel to the vector v. In the frame K' moving with velocity vector v with respect to K, the velocities are respectively
(b) In the K frame the velocities of the particle at the time t and t + dt are respectively
(0,v,0) and (0,v+wdt,0)
where vector V is along x-axis. In the K frame the velocities are
