question

Two inertial systems S and S' have a common x-axis and parallel y-axis, and S' moves with a speed of 0.6c relative to S in the direction of the x-axis. An observer in S sees a rocket moving with a speed of 0.1c in the positive y-direction. What is the speed and direction of the rocket as seen by an observer in the S'-system?

options

  1. 0.2c in the positive y-direction and 0.6c in the negative x-direction resulting from vector addition
  2. 0.605c in a direction making an angle of 7°36' with the negative direction of the x-axis
  3. 0.7c in a direction making an angle of 8° with the negative direction of the x-axis
  4. 0.5c in a direction making an angle of 15° with the positive direction of the y-axis
  5. 0.1c in the positive y-direction with no change in velocity due to the relative movement of S'
  6. 0.6c in a direction making an angle of 10° with the negative direction of the x-axis
  7. 0.7c in a direction making an angle of 20° with the positive direction of the y-axis
  8. 0.68c in a direction making an angle of 11° with the positive direction of the x-axis
  9. 0.5c in a direction making an angle of 5° with the negative direction of the x-axis
  10. 0.605c in the positive y-direction without any angular deviation
