A particle in frame O moves with velocity v = 0.6c on the xy plane. The direction of motion of this particle with the x-axis of the frame O forms an angle of 30∘. Calculate the velocity of this particle and the angle it makes with the x محور axis in the frame O.. Also draw the direction of motion of the particle in the frame O.. In this case, consider the velocity of the frame O ′ relative to the frame O u = 0.8c in the positive direction of the x-axis. Calculate the velocity in c. (The center of the frames and their axes coincided at t = 0.)
