Physics question, only one doesnt have to be too correct, just a good attempt

4. Energyr to sound, time-dependent power, and SIL: Suppose a l-lb bowling ball is dropped from height of 2 m, and hits the ground1 stopping; suppose at! of that kinetic energy is converted to a single sound pulse lasting 0.] seconds. For simplicity. you can assume the sound is a square pulse having constant pressure AP for 0.1 s (and zero everywhere. else), :ie. it is a short \"square pulse". (a) Potential energy to sound: What is the power contained in the resulting sound wave? (b) F all-off, intensity, and SIL: If you're standing 10 m from the event, what SIL do you hear? You can assume the sound spreads over a half sphere (ground prevents it from expanding downward) instead of the simplest full sphere. Based on numbers and our hearing range. do you think a large fraction of the energv in such event is converted to sound
