#10# #"kJ"#

Explanation:

#F# (the force) is #100"N"#

#d# (the distance) is #100"m"#

The time is useless since the work is given by the equation #w=Fdcostheta#

Now, #theta# is the angle between the direction of the applied force and the direction of the motion of the object, in this case it is #0# because the motion of the plow is in the same direction of the applied force (of the horse)

Substituting the values the answer is,

#w=Fdcostheta#

#color(white)w=100(100)(cos0)#

#color(white)w=100(100)(1)#

#color(white)w=10000"J"#

#color(white)w=10"kJ"#
