As we know that work done due a force F is given by formula
[tex] W = F.d[/tex]
here F = applied force due to which work is done
d = displacement of object
now here we will have
W = 588 J
d = 1.4 m
now we can find force by above formula
[tex]588 = F* 1.4[/tex]
[tex]F =\frac{588}{1.4}[/tex]
[tex]F = 420 N[/tex]
So applied force by milkman is F = 420 N
