A child on a bridge throws a rock straight down to the water below. The point where the child released the rock is 51 m above the water and it took 3 s for the rock to reach the water. Determine the rock's velocity (magnitude & direction) at the moment the child released it. Also determine the rock's velocity (magnitude & direction) at the moment it reached the water. Ignore air drag.
