Hiya, folks. I've got what may or may not be a high-school level physics question, but frankly I've never taken a physics class and even more frankly, I'm not sure what terms to search for on Google to find the answer myself.
Consider the following hypothetical circumstances. A spaceship, starting from low-earth orbit, accelerates toward a distant planet (or star or whatever). Assuming the craft accelerates at a constant rate indefinitely (I know, I know - just humor me), how long will it take to get where it's going?
If the craft was headed somewhere, say, 15 light-years away, how long would it take to get there? I assume it would have to decelerate for just as long as it accelerated in order to come to a stop at its destination, so there should be 50% acceleration and 50% deceleration (negative acceleration?) in total, right?
This concept resulted from a conversation with my 10-year-old son, and I told him I'd figure it out, but clearly I'm not as smart as I thought I was. Any help will be appreciated!
