Jill, Jane, and Judy are triplets. Jame remains on Earth. Jill embarks on a starship traveling at 0.6c in the +x direction Judy on another ship is going in the opposite direction (-x) at 0.8c. a) In 1 year, how many light years has Jill traveled as seen in Jane's earth frame? b) In 1 year, how many light years has Judy traveled as seen in Jane's earth frame? c) What does Jane see as the relative speed between Jill and Judy? Any help is desperately needed. Thanks!
