We solved this in class 4 months ago but I just can't remember the solution, or even where to start. I remember rearranging an equation. If an object is dropped from a height and it takes T seconds to hit the ground, how long will it take if dropped from four times the height? Possible answers: A. T seconds. B. √2 T seconds. C. 2T seconds. D. 2 √2 T seconds. E. 4T seconds. Can anyone give me a hint without giving the answer?
