In wagon pulling, there is a harnessing system involved which is attached to the breast of the horse. When a horse pulls forward, the harness, which is attached to the wagon moves with him as well, therefore moving the wagon forward.
Actually, the wagon doesn't pull back on the horse. The horse leans into the collar which causes the wheels to turn. It's basic physics.

20N times 5m equals 100 NewtonMetres, or 100 Joules.

F = M AA = F / M = 30/10 = 3 meters/sec2Neglecting friction in the wheel bearings, air resistance, etc. We also must assume that the pull is exactly parallel to the ground, i.e. perpendicular to the gravitational force.
Work = (force) x (distance)Work = (33N) x (13m) = 429 N-m = 429 joulesIF the force is in exactly the same direction as the motion of the wagon.
Gravity pulls the wagon down the ramp. Friction from the tires on the ground slows the wagon. Wind resistance (friction from the air) slows the wagon as well. Gravity also helps slow the wagon down once it is off the ramp and the wagon is rolling on a level surface.
