A space probe is to travel from Earth to a refueling station 5.05 ly away. At what speed must the probe travel in order for the Earth–station distance to be 2.45 ly, when measured in the reference frame of the probe? Express your answer as a multiple of c, the speed of light in a perfect vacuum. c
A star is 14.7 ly (light-years) from Earth. (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.46 ly? m/s (b) What is the journey's travel time in years as measured by a person on Earth? yr (c)What is the journey's travel time in years as measured by the astronaut? yr

My Notes As shown in the figure below, a galactic patrol spacecraft traveling at a speed of u = 0.940c relative to the Earth is pursuing an enemy spacecraft moving away from the Earth at a speed of r = 0.775c. Enemy spacecraft Galactic patrol spacecral (a) Determine the velocity (expressed as a multiple of c) at which the crew on the enemy craft claims the patrol craft is moving. (Indicate the direction...
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...

These are the answers, please provide the work for the calculation 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.

Xena is going home from an interplanetary travel. Her ship is directed to Earth and is traveling at speed v. When she is at a distance L from Earth (in her reference frame) she sends a signal to her husband Yan to get the dinner ready. In her reference frame the dinner takes a time tD to cook. a) How far is she from Earth when she sends the signal in Yan’s reference frame? b) How long will it take...
