4) A spaceship leaves earth (event A), travels to Alpha Centauri, and then returns to earth exactly 15.0 y later (event B) with respect to clocks on the earth. Alpha Centauri is 4.3 ly from earth. The spaceship's acceleration time is so short that it spends virtually all of its time traveling at a constant speed. a) If the spaceship travels straight towards Alpha Centauri and back again, what is the time between events A and B as measured by...

The nearest star to Earth besides the Sun is Proxima Centauri, which is a distance of approximately 4 light years away. A planet that may be able to sustain liquid water on its surface was discovered in 2016 orbiting Proxima Centauri. According to observers on Earth, a spaceship that travels at 0.9c should be able to reach the planet in 3.6 years. How long would the trip take according to astronauts on board the spaceship?

The distance to a particular star, as measured in the earth’s frame of reference, is 7.87 ly (1 light year is the distance light travels in 1 year). A spaceship leaves earth headed for the star, and takes 3.96 yr to arrive, as measured by passengers on the ship. 1. How long does the trip take, according to observers on earth? Express your answer with the appropriate units. (t = ? yr) 2. What distance for the trip do passengers...

1. Two cells that subdivide on Earth every 10.0s start from the Earth on a journey to the Sun (1.5 x 1011 m away) in a spacecraft moving at 0.850c. How many cells wil exist when the spacecraft crashes into the Sun? Earth time is 588s. Spacecraft time is 310s or 31 cycles of division. 2312.1x 10 cells at the end of the journey. 2.

ANSWER 3A, B, AND C!
3. The star system that is closest to the earth is Alpha Centauri. It is 4.37 light years away in Earth's reference frame. The fastest spacecraft humans have ever launched is New Horizons, which sent us sweet pictures of Pluto in 2015. It attained a speed of 45 km/s relative to the sun. That's fast, but even at this rate, interstellar travel is not practical. a) Traveling at 45 km/s, how long, in years, would...

Having trouble with this. Dont know where to start.
A spaceship travels at 0.540 Co away from Earth. When the ship is 2.57x1011 m away in the Earth reference frame, the ship clock is set to t = 0 and a message (light signal) is sent to its ground crew on Earth. When this message is received the ground crew immediately sends a reply (light signal) to the ship. The ground crew adjust their clocks to specify t = 0...
