The tractor, working on plowing, developed a hook power of 25.8 kW at a travel speed of 25 m / s. How great is the resistance force on plowing?

Initial data: N (the power that the tractor developed while working on plowing) = 25.8 kW (25.8 * 10 ^ 3 W); V (tractor speed) = 25 m / s.

If the speed of the tractor on plowing was constant, then the equality is true: | F | = | Fcomp. | = N / V.

Let’s make a calculation: Fcopr. = 25.8 * 10 ^ 3/25 = 1032 N.

Answer: The resistance force during plowing was 1032 N.
