Question

To estimate the height of a building, a stone is dropped from the top of the building into a pool of water at ground level. The splash is seen 5.1 seconds after the stone is dropped. What is the height of the building? Use the position function below for free-falling objects. (Round your answer to one decimal place.)

s(t) = −4.9t² + v₀t + s₀

Answer 1

s(5.1) =-16(5.1)^2 +0(5.1) + s = 0

16(5.1)(5.1) = s

s = 416.16 feet high
