## Answers

The work done on the block is B) 400 JExplanation:The work done when lifting an object is equal to the change in gravitational potential energy of the object:[tex]W=mg \Delta h[/tex]wherem is the mass of the objectg is the acceleration of gravity[tex]\Delta h[/tex] is the change in height of the objectIn this problem we have:(mg) = 100 N is the weight of the block (product of mass and acceleration of gravity)[tex]\Delta h = 6 m - 2 m = 4 m[/tex] is the change in heigth of the objectSubstituting, we find the work done:[tex]W=(100)(4)=400 J[/tex]Learn more about work:brainly.com/question/6763771 brainly.com/question/6443626 #LearnwithBrainly
