Work is considered as the Force performed on a body to move it a certain distance, that is
W = Fd
Here
W = Work
F = Force
d = Distance
In this case we have the values of work and distance, therefore clearing for the Force we would have to
Replacing,
Therefore the force that Marissa must exert on the windows shade is 0.4N
