Question

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

Answer 1

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

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.

Answer 2

`200,000J=2x10^5J`

Explanation:

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

Force:
`F=2000N`

and the vertical distance that this material is moved:

Distance:
`d=100m`.

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

`W=F*d`

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

Substituting the known values:

`W=2000N*100m\\W=200,000J`⇒This is the work done.

this quantity can also be expressed as follows:

`W=2x10^5J`

So, the work done by the crane is:
`200,000J=2x10^5J`
