This is NOT homework.

In the FBD above, there is no friction, the velocity is constant, and the distance traveled by the box is 10 m horizontally. Find the work exerted on the object horizontally.

if f = 0, and a = 0 because of constant velocity,

ΣFx = ma = Fapp (cos 40) - f

200 kg (0) = Fapp (cos 40) -f

0 = Fapp (cos 40) - f

Fapp (cos 40) = f = 0

thus,

Fapp (cos 40) = 0

does this mean: Work = Fapp (cos 40) (d)

W = 0 (10 m)

W = 0

is this possible, to have no force but achieve distance?

Hi, by the way, I am new here. :)
