Here's a question for you guys
Upon his return from the April 2002 space shuttle Atlantis mission, Purdue alumnus Jerry ross is assigned to take NASA'a latest top-secret test vehicle out for a spin beyond the solar system. He says goodbye to a friend of his who is six months his junior. Upon his return 60 days later (by his watch) he greets his friend and discovers that they are now exactly the same age! Assuming Jerry traveled at a constant speed during his two month journey (the acceleration periods were brief), how fast did he go?
just as a sidenote, I was able to solve this in 3 minutes
