For those of you who are having some difficulty with conversions (seconds to years, years to seconds, etc.) here's a lesson on the topic from the Physics course.

For those of you encountering difficulty with "cube roots" and assuming you're using the TI 30 XIIS calculator, here are a couple Youtube videos showing how to do cube roots using that calculator. 

If you're using something different, I'll bet you can find a tutorial on whatever model you do have.
