Hello
1) The formula to calculate the work done when moving an object is
[tex]W=Fd[/tex]
where W is the work, F is the force applied to the object, and d is the displacement of the object.
2) Therefore, since we know the force [tex]F=80~Kg/m/s^2=80~N[/tex] and the displacement [tex]d=1.25~m[/tex], we can calculate the work done by each woman:
[tex]W=Fd=80~N \cdot 1.25~m = 100~J[/tex]
