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
