The nearest star to Earth is Proxima Centauri, 4.2 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 3.9 years, as measured by travelers on the spacecraft? Express your answer using two significant figures. v=_____c Part B How long does the trip take according to Earth observers? Express your answer using two significant figures. t=_____ 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.
In an Earth reference frame, a star is 76 light-years away. How fast would you have to travel so that to you the distance would be only 39 light-years?

Astronaut Flo wishes to travel to a star 20 light years away and return. Her husband Malcolm, who was the same age as Flo when she departs, stays home (baking cookies). If Flo travels at a constand speed of 80% of the speed of light (except for a short time to turn around), how much younger than Malcolm will Flo be when she returns?Hint--How long does Malcolm sit around baking cookies? How far is the distance to Flo?
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?
A spaceship and its occupants have a total mass of 1.6×105 kg. The occupants would like to travel to a star that is 22 light-years away at a speed of 0.64c. To accelerate, the engine of the spaceship changes mass directly to energy. - Estimate how much mass will be converted to energy to accelerate the spaceship to this speed? Express your answer to two significant figures and include the appropriate units. - Assuming the acceleration is rapid, so the...
Suppose an astronaut travels to a star 10 lightyears away at a significant fraction of the speed of light (for example, v=0) and returns. Assume the negligible amount of time is spent at the destination. Does this round-trip journey take less than, equal to, or more than 20 years as observed by an Earth-based observer? Does this round-trip journey take less than, equal to, or more than 20 years as observed by the astronaut? Describe the journey as the astronaut...
