SUMMARY
A rock dropped from a cliff falls the first half of the distance to the ground in 2.0 seconds. To determine the time taken to fall the second half, one must apply the equations of kinematic motion under constant acceleration due to gravity. The correct approach involves using the formula for distance traveled under constant acceleration, rather than attempting to manipulate time directly. The solution requires a clear understanding of the kinematic equations and the principles of free fall.
