Hello, I am trying to write a scene- story is set a bit in the future in which theoretically, using nuclear as a fuel is a possibility in space travel. The problem I'm trying to solve right now is if a probe is traveling to Alpha centauri (4.37) light years from the sun and the probe accelerates the first hour and decelerates the last hour of travel, how many g forces are placed on the probe if it reaches alpha centauri in 8 years? So basically i only need to know what the G forces would be in the first hour of acceleration. My character is trying to explain to my other character that the g forces needed to accelerate a probe that fast are physically impossible for a human to withstand. I hope my question makes sense but I don't know how to set up the problem to solve.
