(06.09 MC)Imagine a rocket that has the ability to move close to the speed of light. This rocket is traveling at 0.84 c. A clock is on the rocket. How much time would a stationary observer measure 60.00 seconds of elapsed time on the clock? A piece of metal that is 1.52 meters long is on the rocket. How long would this piece of metal appear to a stationary observer? Remember to show work and provide answers with correct units for full credit.
