Rocket A travels towards the Sun at 0.691c with respect to an observer on Earth. Rocket B travels at 0.933c with respect to rocket A in the opposite direction. (Assume rocket B travels the +x direction.) Sun rocket A Earth m rocket B (a) Is rocket B's speed greater in Earth's reference frame or in rocket A's reference frame? O Earth's reference frame O rocket A's reference frame O not enough information (b) How fast (in terms of c) is rocket B traveling with respect to an observer on Earth? Q6 (c) What is the length (in m) of rocket B in Earth's reference frame if rocket B has a length of 4,68 m in its own reference frame?
