A soccer player kicks a lock horizontally of a 46 m high cliff into a pool of water. If the player hears the sound of the splash 3.26 s later, (a)what was the initial speed given to the rock in m/s?assume a speed of sound in air is 343 m/s. (b)What if the temperature near the cliff suddenly falls to 0゚ C reducing the speed of sound of 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 3.26 s after kicking the rock?
