The nearest star to Earth is Proxima Centauri, 4.3 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 4.9 years, as measured by travelers on the spacecraft? b: How long does the trip take according to Earth observers? in years
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 5.3 years, as measured by travelers on the spacecraft? Express your answer using two significant figures. C is the answers unit. How long does the trip take according to Earth observers? Express your answer using two significant figures. years is the answers unit.
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?
Alpha Centauri, the binary star closest to our solar system, is about 4.0 ly away. If a spaceship traveled this distance with a constant speed of 0.85c relative to Earth, how much time would elapse (a) on a clock on the spaceship? Ans in Years
Question 1: You wish to travel to a planet located 10 light years (ly) away. a) How fast must you travel for that distance to be only 2.0 ly as seen from your spaceship? b) How long does it take for you to get there in your time? c) According to your friends on Earth, how long does it take for you to get there?
A starship moving at 0.85c travels from Earth to the Wolf-359 system, 7.9 light years away. How long will the trip take according to a) Earth’s clocks? b) the starship’s clocks? c) How far is it from Earth to the star according to the starship’s crew? d) What do they compute their speed to be?
