A tourist is walking at a speed of 1.9 m/s along a 4.4-km path that follows an old canal. If the speed of light in a vacuum were 2.7 m/s, how long (in km) would the path be, according to the tourist? Number UnitsHow fast must a meter stick be moving if its length is observed to shrink to 0.52 m? Number n Units V A woman and a man are on separate rockets, which are flying parallel to each other and have a relative speed of 0.830c. The woman measures the same value for the length of her own rocket and for the length of the man's rocket. What is the ratio of the value that the man measures for the length of his own rocket to the value he measures for the length of the woman's rocket?
