Question

Какую мощность развивает трактор при равномерном движении на первой скорости, равной 3,6 км/ч, если у трактора сила тяги 12 кн?

Answer 1

N=F*V=12*10^3=12 кВт.                                           

Answer 2

V=3,6км/ч=1м/с
N=F*V
N=12000*1=12000 Вт

Answer 3

Calculating Tractor Power at First Gear

To calculate the power developed by the tractor at a speed of 3.6 km/h on the first gear, we can use the formula:

Power (P) = Force (F) × Velocity (V)

Given: - Force of traction (F) = 12 kN - Velocity (V) = 3.6 km/h

First, let's convert the velocity from km/h to m/s: - 3.6 km/h = 1 m/s

Now, we can calculate the power: - Power (P) = Force (F) × Velocity (V) - Power (P) = 12 kN × 1 m/s - Power (P) = 12 kW

So, the tractor develops a power of 12 kW when moving at a speed of 3.6 km/h on the first gear.
