Final answer:
The magnitude of the change in momentum can be positive, negative, or zero depending on the force applied. Without additional information, we cannot determine the magnitude of the change in momentum in this question.
Step-by-step explanation:
The magnitude of the change in momentum of an object can be positive, negative, or zero, depending on the direction and magnitude of the force applied to the object.
If the force applied to the object causes it to speed up or change direction in the same direction as its initial velocity, the change in momentum is positive. If the force applied to the object causes it to slow down or change direction opposite to its initial velocity, the change in momentum is negative. If the force applied to the object is balanced and does not change its speed or direction, the change in momentum is zero.
In the given question, since no information is provided about the force applied or the direction of change in velocity, we cannot determine the magnitude of the change in momentum without additional information.
