An object of mass 5 kg travels in the positive direction with a speed of 1 m/s. The object collides with a second object that exerts an average net force over an interval of time such that the 5 kg object comes to rest. Which of the following best predicts the change in momentum for the 5 kg object?
A. The change in momentum is in the negative direction.
B. The change in momentum is in the positive direction.
C. The change in momentum is zero. ا
D. The direction of the change in momentum cannot be determined without knowing the value of the average force and time in which the force is exerted.
