Q: A spaceship travels with a speed of 0.6 c as it passes by the Earth on its way to a distant star, as shown in the diagram below. The pilot of the spaceship measures the length of the moving ship as 10 m. Determine its length as measured by a per- son on Earth. Answer in units of m.
The pilot of the spaceship observes that the spaceship travels for 2 years. Determine how much time has passed according to a person on Earth.
Some time after passing the Earth, the pilot shoots a laser pulse backward at a speed of 3 *10 ^8 m/s with respect to the spaceship. Determine the speed of the laser pulse as measured by a person on Earth.
