Suppose astronomers discover a radio message from a civilization whose planet orbits a star 35 light-years away. Their message encourages us to send a radio answer, which we decide to do. Suppose our governing bodies take 2 years to decide whether and how to answer. When our answer arrives there, their governing bodies also take two of our years to frame an answer to us. How long after we get their first message can we hope to get their reply to ours? Enter your answer in years.

The duration  is  

  Generally the time it would take for the message to get the the other civilization is mathematically represented as

Here c  is the speed of light with the value  

=>    

=>    

converting to years

Now the total time taken is mathematically represented as

=>  

=>   [tex]T  =72 \  years /tex]

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
