Two twins, Sam and Sue, start out together on the earth. Sue blasts off in a spaceship and then travels inertially until her clocks show that a year has passed. She then reverses her direction and travels inertially again. When she arrives back on the earth, two more years have passed (on her clocks) for a total of three. When she gets back, Sam is four years older than he was when she left. 0 a) Draw a spacetime diagram that represents Sue's inertial frame as she goes out. o b) According to Sue's inertial frame as she goes out, how far apart are the twins when she turns around? a c) Draw a spacetime diagram that represents Sue's inertial frame as she comes back. a d) According to Sue's inertial frame as she comes back, how far apart are the twins when she turns around
