Solution
Loud noise:
According to the law of conservation of energy, the overall energy states that the total systems remain unchanged, it really only moves through one form towards another, thus sound is also a type of energy.
Loud loudness indicates a lot of energy.
When a whip is cracked, the loop that forms at the tip of the whip travels faster than the speed of sound breaking the sound barrier and henceforth creating a mini sonic boom which results in the creation of loud noise.
