The frictional force on the sofa at the given conditions is 460.4 N.

The given parameters:

  • weight of the sofa, W = 60 N
  • applied force, F = 480 N
  • acceleration of the sofa, a = 3.2 m/s²

The mass of the sofa is calculated as follows;

[tex]W = mg\\\\m = \frac{W}{g} \\\\m = \frac{60}{9.8} \\\\m = 6.122 \ kg[/tex]

The frictional force on the sofa is calculated by taking the net force on the sofa as follows

[tex]\Sigma F = ma\\\\F - F_f = ma\\\\F_f = F - ma\\\\F_f = 480 - (6.122\times 3.2)\\\\F_f = 460.4 \ N[/tex]

Thus, the frictional force on the sofa at the given conditions is 460.4 N.
