Question: The height of a cliff relative to the ocean below is 55.0m. Someone kicks a rock horizontally off of the cliff and hears the sound of the splash 4.5 s later.
Part A: How long does it take for the rock to hit the water?
Part B: How far must the sound travel to get back to the cliff.
Part C: Relative to the base of the cliff where does the rock hit the water?
Part D: What was the initial speed given to the rock?
Rework your solution from the beginning and check each step carefully. Thanks.
