Force (N) 3 2 1. Time (s) 5 6 7! 8 -1 -2 -3 -4 -5- An object is initially at rest. A varying force is applied to the object as shown in the graph. Which of the following correctly explains the momentum of the object at time t = 7 s? The final momentum of the object is negative because the slope of the graph is negative the entire time from t = 0 s to t = 7 s. A The final momentum of the object is positive because the maximum magnitude of the force in the positive B direction is twice the maximum magnitude of the force in the negative direction. The final momentum of the object is negative because the magnitude of the area bounded by the graph and the horizontal axis is less from t = 0 s to t = 2 s than from t = 2 s tot = 7 s. The final momentum of the object is positive because the average magnitude of the force is higher from t = 0 s to t == 2 s than the average D magnitude of the force from t = 2 s to t = 7 s.
