i have a feeling the answer would be C.

anonymous · Answer

I think d is correct

anonymous · Answer

No, thats a popular misconception like aristotle's physics. Aristotle, while a great man, is totally and utterly wrong about physics. Mass has nothing to do with rate of fall.

The answer is B. If you remember, the equation for potential energy is $$U=mgh$$ and at the bottom potential energy is converted to Kinetic energy. Therefore U=KE at the bottom.
$$U=KE=mgh$$

D is also correct. There is more height, therefore according to kinematic equations. $$v_f^2=v_i^2+2ad$$

actually v final and h are not directly proportional so the answer should just be b
