g The distance from New York to Los Angeles is about 4,900 km and should take about 49 h in a car driving at 100 km/h. (Note: for u ≪ c, 1 − u2/c2 ≌ 1 − 1 2 u2 c2 and 1 1 − u2/c2 ≌ 1 + 1 2 u2 c2 . Do not solve this problem numerically until the last step of the calculation; your calculator may not register the correct answer.) (a) How much shorter than 4,900 km is the distance according to the car travelers?
