SHM Position Function 2

APPH12-MZKEGE

A certain simple harmonic oscillator vibrates with a period of 2 seconds.

If SI units are understood on all of the following functions, which one could possibly be a correct function for the oscillator's position as a function of time?

A

$x = 2\cos { \left( 3\pi t \right) } $

B

$x = 5\sin { \left( 2\pi t \right) } $

C

$x = 7\sin { \left( \pi t \right) } $

D

$x = 3\cos { \left( 4\pi t \right) } $
