# Kinematics: A Rock Thrown Downwards

A rock is thrown straight downward with an initial speed of 3m/s into a well. As the same time, the bucket 110 meters down at the bottom of the well is raised at a speed of 2m/s. Determine how far the rock has fallen when it hits the bucket. (Use g = 10 m/s^2).
