Answer:

W = 40 J

Explanation:

The work done by a force is defined as the dot product of the force and displacement of the object. Therefore, the following formula can be used to find the work done:

[tex]W = F.d = Fd Cos\theta\\[/tex]

where,

W = Work Done = ?

F = Force = Weight of Block = 4 N

d = distance lifted = 10 m

θ = angle between force and displacement = 0°

Therefore,

[tex]W = (4\ N)(10\ m)(Cos\ 0^{0})[/tex]

W = 40 J
