Question

A rock is dropped off of a bridge into the water below. If the initial velocity was zero, and the well is on Earth (g = 9.8 m/s2), and you see the splash 4.59 seconds after the rock was dropped, how high was the bridge above the water? Give your answer in meters, to the nearest tenth of a meter.

Answer 1

h = (1/2)(9.8)(4.59)^2
