11. . A meterstick moves past you at great speed. Its motion rela- tive to you is parallel to its long axis. If you measure the length of the moving meterstick to be 1.00 ft (1 ft = 0.3048 m)-for example, by comparing it with a 1-foot ruler that is at rest rel- ative to you, at what speed is the meterstick moving relative to you?
