Suppose that a particle moves relative to O' with a constant velocity of c/2 in the x'y'-plane such that its trajectory makes an angle of 60 with the x'-axis. If the velocity of O' with respect to O is 0.6c along the x-x' axis, then the equations of motion of the particle as determined by O are Ox=0.74 ct, y = 0.43 ct Ox=0.30 ct, y = 0.74 ct O x = 0.74 ct, y = 0.30 ct O x=0.43 ct, y = 0.23 ct
