- A day on the Earth has 24 hours. How fast must a spacecraft travel so that the spacecraft clocks tick through 23 hours (on spacecraft clocks) while the earth clocks tick through 24 hours from the viewpoint of an observer on the Earth?A rocket is travelling from earth through space at a speed of 2.7x10^8m/s. The pilot measures the journey to take 240 minutes. How long does mission control on Earth think the flight lasted for?A group of astronauts travel to a nearby star system and back to earth at a velocity of 0.98c (98% of the speed of light) relative to earth. According to the astronauts' clocks, it takes them approximately 8 years to make the journey. Use the time dilation formula to determine how much time has passed on Earth in their absence.

A friend is on Earth, and an astronaut in another rocket is moving toward Earth at one-third the speed of light (in the Earth reference frame), on a path collinear with your path. If each of you records the duration of your journey in your three respective reference frames, which of you records the proper time interval?
- help on this please!!The distance to a particular star, as measured in the earth's frame of reference, is 7.11 light- years (1 light-year is the distance that light travels in 1 y). A spaceship leaves the earth and takes 3.35 y to arrive at the star, as measured by passengers on the ship. (a) How long does the trip take, according to observers on earth? (b) What distance for the trip do passengers on the spacecraft measure?Two atomic clocks are synchronized. One is placed on a satellite which orbits around the earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks can measure time accurately to many significant digits. a)Will the two clocks still be synchronized after one year? b) imagine the speed of light is much lower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning using a calculation.
