Spacecraft I, containing students taking a physics exam, approaches the Earth with a speed of 0.660c (relative to the Earth), while spacecraft II, containing professors proctoring the exam, moves at 0.260c (relative to the Earth) directly toward the students. The professors stop the exam after 84.0 min have passed on their clock. (a) For what time interval (in minutes) does the exam last as measured by the students? min (b) For what time interval (in minutes) does the exam last as measured by an observer on Earth? 87.024 min What If? Suppose one of the professors proctored the exam by traveling on spacecraft I and stopped the exam after 84.0 min elapsed on her clock. (c) For what time interval (in minutes) does the exam last as measured by the professors on spacecraft II? min (d) For what time interval (in minutes) does the exam last as measured by an observer on Earth? min
