Question

piece of roof ballast (stone) that falls (effectively, is released from rest) from the top of a building travels 12.8 m in the last second before it hits the ground. How high is the building? By the way, describing a projectile as stone (vs hollow plastic, for example) is one way to imply that air resistance is likely to be negligible in comparison to gravity.
