If the acceleration of an object is constant, the value of the acceleration may be determined by any of the following methods except:
1) Dividing the change in the object's velocity by the time interval over which the velocity changed.
2) Dividing the average velocity of the object by the time interval over which the average velocity was measured.
3) Dividing the constant force acting on the object by the object's mass.
4) Finding the slope of the object's velocity-time graph.
5) Dividing twice the distance the object travels from rest by the square of the travel time.
