Answer:
Distancia, S = 136 metros
Explanation:
Dados los siguientes datos;
Aceleración, a = 3 m/s²
Velocidad inicial, u = 5 m/s
Tiempo, t = 8 segundos
Para encontrar la distancia recorrida, usaríamos la segunda ecuación de movimiento;
S = ut + ½at² Sustituyendo en la fórmula, tenemos;
S = 5 × 8 + ½ × 3 × 8²
S = 40 + 1,5 × 64
S = 40 + 96
Distancia, S = 136 metros
Answer:
Power of the speakers = 1.57 
Explanation:
There are speakers setup in a park and we have to find the power it would require to have intensity of sound to be 
at a distance of 5 meter.
In one dimension the intensity is constant as the wave travels. In two or three dimensions, however, the intensity decreases as you get further from the source.
Intensity is inversely proportional to the square of the distance from the point of sound production.
Here area = 2
area = 157 
Power = ![10^{-8} \times 157Power = 1.57 [tex]\times 10^{-6} W](https://tex.z-dn.net/?f=10%5E%7B-8%7D%20%5Ctimes%20157%3C%2Fp%3E%3Cp%3E%3Cstrong%3EPower%20%3D%201.57%20%5Btex%5D%5Ctimes%2010%5E%7B-6%7D%20W)
