A reference frame S' moves with a constant speed v=0.800c along the x axis relative to a second reference frame S. A particle is observed from reference frame S' to be moving with velocity 0.400c (along the positive x' axis). What would be the velocity of the particle as measured by an observer in reference frame S?

Answer : 8.66 ns
uppose an object with a rest length of 10 ns is at rest in a frame that is moving with a speed of 0.50 relative to the Home Frame. Draw a two-observer spacetime dia- gram of this situation, and use it to determine the length of the object in the Home Frame. Check your result by using equation R6.2.
