Consider motion in one dimension. (The sign of the vector quantities is their direction indicator.) An object moves in the positive x-direction with speed 3.2 m/s for 1.9 s. It stops for 3.5 s and then moves in the negative x direction with speed 1.9 m/s for 3.5 s. What is the displacement of this object in units of meter? Enter a number with two digits behind the decimal point.
