How much work is done by a crane that raises 2000 N of material a distance of 100 m

Step-by-step explanation:

Since there are 2000N of material, the force needed to lift it must be equal to the weight of this material.

Force:

and the vertical distance that this material is moved:

Distance: .

Now, to calculate the work done we use the following formula:

Where W is the work done, F is the force applied, and d is the distance moved.

Substituting the known values:

⇒This is the work done.

this quantity can also be expressed as follows:

So, the work done by the crane is:

The work done by the crane is 200,000 Joules.

Step-by-step explanation:

Hi, to answer this question we have to apply the work formula:

Work = force x distance

Replacing with the values given and solving for w:

W = 2000 N x 100 m = 200,000Nm = 200,000 Joules

In conclusion, the work done by the crane is 200,000 Joules.

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
