Question

T=sqrt(2h-40t/g) I'm not sure where to even start on this one.

Answer 1

`\bf T=\sqrt{\cfrac{2h-40t}{g}}\impliedby \textit{then we square both sides} \\\\\\ T^2=\left( \sqrt{\cfrac{2h-40t}{g}} \right)^2\implies T^2=\cfrac{2h-40t}{g}\implies gT^2=20h-40t \\\\\\ gT^2+40t=20h\implies \cfrac{gT^2+40t}{20}=h`
