#2 is sound deductive. The book says that it is.

physics
So is the formula for r: r = (1/4)(v^2/g)? or (1/4 v^2)/g ? sorry I am asking so much

physics
So the first formula period=2pi*sqrt(r/g) is incorrect? I am just confused I am sorry

physics
I am just confused on the way some of these are written out like in the period equation you just gave, is pi multiplied by v and then divided by g or is the whole quantity given by v/g multiplied by pi?

physics
Is the formula r = (1/4)(v^2/g)? or (1/4 v^2)/g ?
