Question

You and your neighbor are mowing your lawns. If your neighbor pushes a lawnmower five time as far as you do but exerts only a half of the force, which one of you does more work and by how much? Remember to show all your work to explain your answer.

Answer 1

It is quite simple

Say, the work done by you is w

such that, the force exerted by you is F

and, the displacement is s

IN THIS CASE.

work done by you(w)=Fs

Now,

CONSIDER THE CASE OF YOUR NEIGHBOUR

let, the work done by him be W

GIVEN, force is half,i.e F/2

and displacement is 5 times

so, work done(W)= F/2*5s

hence, W= 2.5Fs

hence, the neighbour does more work. HE DOES 2.5 TIMES MORE WORK THAN YOU
