Two rockets are approaching each other on a collision course. Relative to a stationary observer on the ground, rocket 1 has speed 9/10 c, and rocket 2 has speed 8/10 c. The stationary observer measures both rockets to have the same length L. According to the stationary observer, the rockets collide after a time t. (a) What are the proper lengths of the rockets? (b) According to one of the rockets, what is the speed of the other rocket? (c) According to rocket 1, how much time elapses before the crash occurs? According to rocket 2?
