Stones are thrown horizontally, with the same initial velocity, from the tops of two different buildings, A and B. The stone from building A lands 4 times as far from the base of the building as does the stone from building B. What is the ratio of building A's height to building B's height?
since the horizontal speed is the same and does not change, since stone A went 4 times as far, building A is 4 times as tall.
Since the horizontal speed is the same and the object is in free fall, distance actually equals the square of time. and since the stone from building A spent 4 times as long in the air as stone B, the ratio is 16
