I2/I1 = (r2)^2/(r1)^2 square root of (I2/I1) = r2/r1 This will be the difference between the two. Therefore (distance between the two people/ square root of (I2/I1)) = smallest distance from loud speaker. And distance between the two people minus the smal...

Log10(I2/I1) = 1/10 (dB2 - dB1) 10^[0.1(dB2-dB1)] = I2/I1

I think the best way to do this is to choose the bottom right corner as the pivot point. Then you get 8*9.8*0.2 = p * 0.4 therefore p = 39.2 for the horizontal force
