Work done by the mover on the refrigerator

The work done by the mover on the refrigerator is calculated as follows;

W = Fdsinθ

W = mgd x sin(θ)

where;

  • m is mass of the load
  • d is the distance traveled by the load

W = 185 x 9.8 x 10 x sin(11)

W = 3,459.37 J

Thus, the work done by the mover on the refrigerator is determined as 3,459.37 J.
