Thanks to everyone. I'm really learning here, I must admit! Never knew there was so many other particles! Geez, we could go on forever I guess. Where the hell did that come from? One moment we're talking about subatomic particles which I was actually learning, and now the above quote comes up...

oh ok. I think i got it. See below steps: we use the formula v^2 = u^2 + 2as because we are trying to find the speed of the divers. we already know that u=0, a=9.8, and s=36m(displacement) v^2 = (0^2) + (2*9.8*36) v = sqrt705.6 v approx = 26.56m/s^-1then using the fact that v = 26.56m/s: v =...

cool. cheers for that alcalder thanx so much:wave:

thanx but i don't get it, but where does the "s" come from. the "s" represents time doesn't it? i think u forgot that 9.8 is actually 9.8m/s^-2. a= 9.8m/s^-2 u= 0 v = ? s? = (time?) Why do we need to use: v^2 = u^2 + 2as (u = 0) ????????????????????

OMG!!!!!!!!! Thankyou so much idling fire I can't believe I didn't think of that!:o Thanks again. Cheers:wave:

Q: Why can't you measure the instantaneous velocity of an object with a stopwatch? Has it got anything to do with: velocity changing constantly need to measure average velocity in a short segment etc.??????????????????? Any help would be appreciated.

Q: A cyclist rides round a circular track at a steady 20m/s. Is this a case of uniform velocity? Explain your answer... I think the answer is no becuase a circular track means that the cyclist will return to their point of origin with each lap and therefore there is no real displacement. Am I...

ahh. Ok. Got it. Thanks everyone. Really appreciate it. Good luck with ur studies. Cheers

thanx alcalder, so, 4 e.g if it was light from air to water: n2 = 1.33 and n1 = 1.00028 So in that case, you take 1.33/1.00028 = constant? and if it was light from water to air: n2 = 1.00028 and n1 = 1.33 So in that case, you take 1.00028/1.33 = constant? Also, my teacher mentioned something...
