Question

As measured by an observer on the earth, a spacecraft runway on earth has a length of 5000 m. Speed of light is 3.0 × 10? m/s. (a) What is the length of the runway as measured by a pilot of a spacecraft flying past at speed of 2.4 × 10? m/s relative to the earth? (b) An observer on earth measures the time interval from when the spacecraft is directly over end of the runway until it is directly over the other end. What value does he obtain? (c) The pilot of the spacecraft measures the time it takes her to travel frome one end of the runway to the other end. What value does she find?
