Answer:
1.
Distance = 0.921 meters
2.
Work = 13.9 kJ
3.
The neighbor
Double your work
Explanation:
1.
Work = Force × Distance
Distance = Work / Force
Distance = 174J /189 N
Distance = 0.921 meters
2.
Work = force × distance
Work = (613 N) (22.6 m)
Work = 13,900 J
Work = 13.9 kJ
3.
Work is a product of force and distance, expressed as W=Fd where W is work in Nm, F is applied force and d is the distance in m
Since your neighbor pushes 4 times then you just push 1m when he pushes 4m, that is an example. Also, since the neighbor only exerts half the force i.e. 0.5N then you exert full force of 1N
Work from your neighbor will be 4d*0.5F=2dF
Work from you will be dF
Clearly, 2dF=2(dF) hence the neighbor exerts double work
