How many seconds in a year?
Besides giving me the answers to the questions below, how did you arrive at them?
How many years = a billion seconds?
How many minutes in a year?
How many years ago was a billion minutes?
What year was it a billion days ago?
What year was it a billion hours ago?
If you drop a ball from above your head, at what point does it have
the most potential energy? At what
point does it have the most kinetic energy?

These are homework questions. And to make matters worse, they're not
even very hard problems. I mean really- if you can't figure out how to
calculate number of seconds in a year, then I assume you don't even
know how many seconds are in a minute, the number of minutes in a day,
and the number of days in a year. And the part about potential vs
kinetic energy? That doesn't even require any math. You just don't pay
attention in class.

So funny I just felll from the chair :)

Heh, heh. I hope you started your fall with little potential energy,
and aquired equally little kinetic energy by the time you collided
with the floor. Otherwise you could get hurt. :)

I was totally going to answer these questions but you didn't specify
if a year had 365 or 365.25 days in it.  However if you want a good
start you could listen to the rent soundtrack.

"However if you want a good start you could listen to the rent soundtrack."

   Ah, yes. A few days ago my kid was watching Rent on home video in
another part of the house. I'd never heard any of the score before,
and all I could hear was something about "Five hundred twenty five
thousand six hundred minutes." I wondered what was significant about
that amount of time. So I picked up my calculator, starting doing the
arithmetic, and then said "Oh, I get it."
