Which of the following statements are true regarding an object in freefall?  You can ignore air resistance for this question. Select all that apply.   A. A heavier object will fall faster than a lighter object.   B. A ball is dropped off a tall tower.  After 3 seconds the ball has fallen 45 m.  This means its final velocity at that point is 15 m/s.   C. The only force acting on an object in freefall is the force of gravity.   D. An object is thrown upward.  As it moves upwards its speed will decrease by 10 m/s each second.   E. A ball is dropped from a tall tower.  As it falls it will travel 10 m for each second that it falls.   F. A ball is thrown up into the air.  At the very top of its path, the acceleration on the ball is 0 m/s/s
