1. An observer sees a spaceship, measured to be 100 m long when at rest, pass completely in uniform motion with a speed of 0.500c. While this observer is watching the ship, a time of 2.00 s elapses on a clock on board the ship. (a) What is the length of the ship as measured by the observer? (b) What time interval elapses on the observer's clock during the 2.00 s interval on the ship's clock? (a) L= (b) At = 1.
