Question

How do you derive this formula?

Answer 1

You use the chain rule: So sqrt, is the same as whole to the (1/2) power.

Answer 2

GO from there: Like so: \[v_i = \sqrt{\frac{ gR^2 }{ 2H }}= ({\frac{ gR^2 }{ 2H }})^{\frac{ 1 }{ 2 }}\]

Answer 3

so it would look like (gR^2/2H)^1/2

Answer 4

Yup, and go from there.

Answer 5

hold on give me a sec please

Answer 6

No rush.

Answer 7

is it (gR^2/ sqrt 2H)
