What power does the tractor develop with uniform movement at the first speed equal to 3.6 km h

What power does the tractor develop with uniform movement at the first speed equal to 3.6 km h, if the tractor has a traction force of 12 kN.

Tractor power can be calculated using the formula:
N = F * V, where N is the tractor power (W), F is the tractor traction force (F = 12 kN = 12 * 10 ^ 3 N), V is the tractor speed (V = 3.6 km / h = 3, 6 * 1000/3600 s = 1 m / s).
Let’s calculate the tractor power:
N = F * V = (12 * 10 ^ 3) * 1 = 12 * 10 ^ 3 W = 12 kW.
Answer: The tractor power is 12 kW.
