# Easy Question?

If a high diver plunges from 36m above the water, what is the length of the time interval during which the diver falls through the air? - assume that throughout their dive, the diver is falling vertically from rest with an acceleration of $$10\ ms^{-2}$$

I'm not sure how to answer this. I think I'm missing something really basic here.

Thanks for your help.

Could you list the equation(s) you think are relevant to this problem? Hint: kinematic equations.

Oh. I've got it now. $$x=\frac{at^2}{2}$$. I missed that one when I looked through my formulas.

Thanks
