Answer:

W = 260 J

Step-by-step explanation:

Work is defined by

W = F. d

Bold type indicates vectors,

W = F d cos θ

where tea is the angle between the force and the displacement, in this case the force is parallel to the displacement so the angle is zero and the

cos 0=1

let's calculate

W = 40 6.5

W = 260 J
