An object oscillates with simple harmonic motion along the x axis. Its displacement from the origin varies with time according to the equation x $=(2\mathrm{.}00)$ cos$($t $+$ $/4)$ m where t is in seconds and the angles in the parentheses are in radians. Determine the period T of the motion. A$)$ T $=1$ s B$)$ T $=2$ s LO: $65,66$ C$)$ T $=4$ s D$)$ T $=12$ s E$)$ T $=14$ s
