(a)a soccer player kicks a rock horizontally off a 35 m high cliff into a pool of water. if the player hears the sound of the splash 2.83 s later, what was the initial speed given to the rock (in m/s)? assume the speed of sound in air is 343 m/s.(b)what if? if the temperature near the cliff suddenly falls to 0°c, reducing the speed of sound to 331 m/s, what would the initial speed of the rock have to be (in m/s) for the soccer player to hear the sound of the splash 2.83 s after kicking the rock?
