When measuring sound intensity levels, the human ear's varying sensitivity to different frequencies is accounted for by using weighted scales like A-weighting, which adjusts measurements to reflect how humans perceive sound intensity across frequencies.

Solution:
F_{{net}} = m × a
F_{{net}} = 750 {kg} × 1.2 {m/s}^2 = 900 {N}
2000 {N} - F_{{friction}} = 900 {N}
F_{{friction}} = 2000 {N} - 900 {N} = 1100 {N}
