The work done: 3500 J
Further explanation
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x D
W = Work, J, Nm
F = Force, N
D = distance, m
a woman is pushing a grocery cart with a 500 Newton force along the 7 meters aisle, so :
F = 500 N
d = 7 m
[tex]\rm w=F\times d\\\\w=500\times 7\\\\w=\boxed{\bold{3500~J}}[/tex]
