Answer 2

its a standard equation. do u want to know how to derive it?

Answer 3

yes

Answer 4

which numbers to plug in @physo

Answer 5

for the derivation, you start with the sum formula, a=-xw^2, where w=omega=2pif=angular velocity. so, you'll have w=(a/x)^0.5. Since a=kx/m for springs, you substitute that in the equation and you end up with that formula

Answer 6

what to plug in? well, you just have to put 2 for T

Answer 7

sorry for the typo, i meant SHM and not "sum formula"
