Answer:
[tex]200,000J=2x10^5J[/tex]
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: [tex]F=2000N[/tex]
and the vertical distance that this material is moved:
Distance: [tex]d=100m[/tex].
Now, to calculate the work done we use the following formula:
[tex]W=F*d[/tex]
Where W is the work done, F is the force applied, and d is the distance moved.
Substituting the known values:
[tex]W=2000N*100m\\W=200,000J[/tex]⇒This is the work done.
this quantity can also be expressed as follows:
[tex]W=2x10^5J[/tex]
So, the work done by the crane is: [tex]200,000J=2x10^5J[/tex]
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.
