Question

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

Answer 1

Answer:

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

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: $F=2000N$

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: $200,000J=2x10^5J$

Answer 2

Answer: 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.
