A mass oscillates back and forth $($left and right$)$ on a horizontal spring with period $T=2\mathrm{.}0s.$ If the mass is pulled to the right and then released, how long will it take for the mass to reach the leftmost point of its motion?

$1\mathrm{.}0$s

$1\mathrm{.}4$ s

$2\mathrm{.}0$s

$2\mathrm{.}8$ s
