Answer
$-0.20$ m.
Work Step by Step
Since the velocity of the object is zero at $t=0$ s, the object is either at its maximum displacement or negative maximum displacement. The slope of the velocity graph at $t=0$ s is positive, therefore, the acceleration and force must be positive. For the force to be positive, the position must be negative. Therefore, the position is the negative maximum displacement, $-0.20$ m.
