Estimate what was the initial speed given to the rock

Reference no: EM13709751

Compute all parts of given question:

Question: The Height of a cliff relative to the ocean below is 57 m. Someone kicks a rock horizontally off of the cliff and hears the sound 4.62s later.

Part I: How long does it take for the rock to hit the water?

Part II: How far must the sound travel to get back to the cliff? Assume that sound moves in a straight line with a speed of 343 m/s.

Part III: Relative to the base of the cliff, where does the rock hit the water?

Part IV: What was the initial speed given to the rock?

Please show me step by step or type in formulas used. I am so lost!!
