Can anyone help me out with this problem: A ball is thrown vertically upward with initial velocity v. Find the maximum height H of the ball as a function of v. Then find the initial velocity v required to achieve a height of H.

we'll just use the eq, \(v^2 = u^2 +2aS\), since u=0, a=g,(since it is opposite direction of v), rearranging gives \(S=\frac{v^2}{2g}\)

ive arrived at this answer too...however when i submitted it...it said that g was not defined in this context

is there any way to answer this in terms of H and v only?

or, you can just sub g=10 into it

thats what i would think so too. but it still says that answer is incorrect

oh oh. sorry. my mistake. it's initial velocity, not end velocity. since v=0, \(u=\sqrt{2gH}=\sqrt{19.8H}\)
