spaceship travels at a speed of 0.95c to the nearest star, Alpha Centauri, 4.3 light years (ly) away. How long does the trip take from the point of view of the passengers on the ship?

A. 1.4 ly

B. 1.0 ly

C. 4.5 ly

D. 14 ly

E. 0.44 ly

Solutions

Expert Solution

In Earth's frame, the time taken by the ship is

                              

Now we have to calculate the time in passengers frame of reference. i.e. we have to calculate the proper time, which can be calculated as

                              

                                        

For any doubt please comment.

Modern Physics A trip is planned to to visit the Alpha Centauri star system 4.3 light years away. Provisions are put in place to allow a trip of 16 years' total duration. How fast must the spacecraft travel if the provisions are to last? Neglect the period of acceleration, turnaround, and visiting times. Express your answer as a multiple of c.

An uncrewed mission to the nearest star, Proxima Centauri, is launched from the Earth's surface as a projectile with an initial speed of 42.9 km/s, just enough for the spacecraft to escape the Earth's gravity and leave the solar system. Ignoring air resistance and the Earth's rotation, what is the speed of the spacecraft when it is more than halfway to the star? Assume we are ignoring the effect of the Sun on the spacecraft.
