1. A stone is dropped from the top of a tower \(750\) \(m\) high into a pond of water at the base of the tower. Calculate the number of seconds for the splash to be heard? (\(g\) \(=\) \(10\) , speed of sound in air \(=\) \(340\) \(m/s\))?
Which equation of motion can be applicable in this case
The time taken by the stone to reach water is \(s\)
The time taken by the sound to reach top surface is \(s\)
Thus, the total time taken by the splash sound to reach the top is \(s\)
