My physics is so rusty and I'm at work so I can't dig out my books but I have a quick question. What is the formula to solve for time if one knows acceleration and distance? Example: if one accelerates 10m/s/s for 1000km, how long does it take to cover the distance? Anyone remember acceleration equations or have them handy? Thanks PS this isn't homework I'm trying to explain something to a co-worker and I'm just really rusty.
