A worker pulls a crate a distance $17\mathrm{.}39$ m along the floor.$$ The crate has a mass of $155$ kg$.$ The tension in the rope that is pulling the crate is $257$ N$,$ and the rope is at a $13\mathrm{.}6$ degree angle above the floor.$$ There is a $20\mathrm{.}7$ N kinetic friction force acting on the crate from the floor.

How much work is done by the normal force the floor exerts on the crate during the trip? Work has units of energy$---$Joules in S$.$I. units.
