A Cartesian coordinate graph with a horizontal time axis labeled t (s) and a vertical net force axis labeled F_{net} (N). The horizontal axis has major tick marks at 0, 1, 2, 3, 4, and 5. The vertical axis has major tick marks at 0, 2, and 4. The graph features light gray gridlines at each integer tick mark. A solid horizontal line segment is plotted at F_{net} = 4 from t = 0 to t = 2. A vertical dashed line connects (2, 4) down to (2, 0). A solid horizontal line segment lies directly along the horizontal axis at F_{net} = 0 from t = 2 to t = 5. No other labels, lines, text, or axes appear.
Net force versus time for a cart moving along a horizontal track.
A cart of mass \(2.0\text{ kg}\) moves along a straight, horizontal track. The cart is released from rest at time \(t = 0\text{ s}\). A single horizontal net force \(F_{\text{net}}\) is applied to the cart as shown in the graph. Which of the following statements correctly describes the motion of the cart during the time interval from \(t = 2\text{ s}\) to \(t = 5\text{ s}\)?
