a. You and a friend pass each other in spaceships that are each traveling 0.77c relative to the other. Your friend takes a nap and you decide to time how long your friend's nap takes. In your frame, your friend's nap takes 2.8 h. How long was your friend's nap in their frame? (Note:In hours) b. Unbeknownst to you, another person on your friend's ship saw you timing your friend's nap and decided to time how long you were timing your friend's nap. In that person's frame (which is the same as your friend's frame), how long were you timing your friend's nap? (Note:In hours)
