SUMMARY
The problem involves calculating the height of a cliff based on the time it takes for a rock to fall and the sound of the splash to return. The total time given is 3.4 seconds, which includes both the fall time and the sound travel time. The correct approach requires setting up two equations: one for the distance the rock falls and another for the distance the sound travels. The height of the cliff is approximately 56 meters, but the fall time is less than 3.4 seconds, necessitating a system of equations to solve accurately.
PREREQUISITES
- Understanding of kinematic equations, specifically r = ut + 1/2at²
