Two identical stones, A and B, are thrown from a cliff from the same height and with the same initial speed. Stone A is thrown vertically upward, and stone B is thrown vertically downward. Which of the following statements best explains which stone has a larger speed just before it hits the ground, assuming no effects of air friction?
(a) Both stones have the same speed; they have the same change in Ug and the same Ki.
(b) A, because it travels a longer path
(c) A, because it takes a longer time interval
(d) A, because it travels a longer path and takes a longer time interval
(e) B, because no work is done against gravity
