Took Emma to the beach everyday and made sand castles, and studied logarithms in the afternoons. Log fires in the evenings. Very nice

You off anywhere this year?

]]>that's Exactly what you call them!!

I had forgotten he he . .

]]>I see now.

Unit for Acceleration (m/s)/s

Derived units.

Cool, happy now

]]>That's the general way with experimental data. Although you can ask for decimal points too.

]]>Thanks for that, I didn't know about the accuracy. That's handy to know and makes sense too, kind of like Amdahls's Law for functions, although none of my tutors have ever mentioned it.

Just shows you that you should always consult others rather than taking one persons word for it.

]]>How is it that s is -2 though kg is -1. Does it just denote that m/s is a ratio and kg is a definite unit?

s is -2 coz its meter per second squared (unit of acceleration).

understand it like this..

As you can see, it appears to be a ratio but is rather a "Rate of Change w.r.t Time"!

Did you get the same units I did? 5.962 is 4 significant digits. Question is slightly off. You can never get more significant digits that than the least accurate input. In this case 9.8 is the least precise input with 2 significant digits. Therefore all rounding if I remember correctly is to 2 significant digits.

m/s is read meters per second.

]]>Yes, I got

, it asked for the answer to 3d.p.How is it that s is -2 though kg is -1. Does it just denote that m/s is a ratio and kg is a definite unit?
