Question

Calculate the work needed to lift a block weighing 4 Newton’s a distance of 10 meters. Help me please.

Answer 1

W = 40 J

Step-by-step 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:

`W = F.d = Fd Cos\theta\\`

where,

W = Work Done = ?

F = Force = Weight of Block = 4 N

d = distance lifted = 10 m

θ = angle between force and displacement = 0°

Therefore,

`W = (4\ N)(10\ m)(Cos\ 0^(0))`

W = 40 J
