If the magnitude of the change in velocity of an object is reduced by a factor of 3 and the time between the initial and final points is the same, which of the following statements must be correct?
The magnitude of the object's average acceleration stays the same.
The average acceleration of the object and its change in velocity vector now point in opposite directions.
The magnitude of the object's average acceleration is reduced by a factor of 3.
The magnitude of the object's average acceleration is increased by a factor of 3.
The average acceleration of the object and its change in velocity vector still point in the same direction.
