The horse carries a load weighing 200 kg on a flat horizontal road, developing a traction force of 750N. Identify the work done by the horse on the 440m path.
Initial data: m (weight of the load carried by the horse) = 200 kg; when moving along a horizontal road, the displacement vector coincides with the speed vector (cosα = 1); F (horse pulling force) = 750 N; S (the path the horse traveled) = 440 m.
The work that the horse has done on a given path is determined by the formula: A = F * S.
Calculation: A = 750 * 440 = 330,000 J (330 kJ).
Answer: The horse will perform mechanical work equal to 330 kJ.
