An object moves so that its position depends on time as x =+12 m – (4 m/s)t + (1 m/s²)t2. Which statement below is not true? O The object is accelerating. The acceleration of the object is +2 m/s? The object stops for an instant at t = 2.0 s. The object first moves in the negative direction and then in the positive direction. The speed of the object is always decreasing.
