$10$ $10$ $kJ$ $"kJ"$

Explanation:

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

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

The time is useless since the work is given by the equation $w = F d cos θ$ $w=Fdcostheta$

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

Substituting the values the answer is,

$w = F d cos θ$ $w=Fdcostheta$

$w = 100 (100) (cos 0)$ $color(white)w=100(100)(cos0)$

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

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

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