A rocket moves with a velocity of 0.92 c to the right with respect to a stationary observer A. An observer B moving relative to observer A finds that the rocket is moving with a velocity of 0.95 c to the left. What is the velocity of observer B relative to observer A (Hint: Consider observer B's velocity in the frame of reference of the rocket.)
