Answer 4

That's the first few digits of pi. :-). Often shorted to 3.14

Answer 5

oh the pi lol my bad :)

Answer 6

so the answer is 1.25s :)?

Answer 7

Hehe. No worries.

The equation that Rapheal presented comes straight from the text on simple harmonic motion. It's derivation lies in differential equations.

Answer 8

yes

Answer 9

I have a another questions as well..may I ask?

Answer 10

Please post as another question. It keeps things organized.
