You have probably never noticed time dilation effects in everyday life. Do some calculations to see why this is. (a) Calculate the speed that a friend would have to move with respect to you so that your measured time intervals are 1.00% larger than hers. That is, for each 100 elapsed seconds on her wristwatch, 101 seconds elapse on yours. (b) How many times larger is the speed you just calculated than the speed of an orbiting space shuttle, 8.00Ã103 m/s?
