Question

Какую силу тяги может развить электровоз мощностью 2000 квт при скорости джижения 20м/с?

Answer 1

Дано:
N = 2 000 кВт = 2 000 000 Вт
V = 20 м/с

F - ?

Из формулы:
N = F*V находим
F = N / V = 2 000 000 / 20 = 100 000 Н или F = 100 кН

Ответ: Сила тяги 100 килоньютонов

Answer 2

Electric Locomotive Thrust Calculation

To calculate the force of traction that an electric locomotive with a power of 2000 kW can develop at a speed of 20 m/s, we can use the formula:

Force of Traction (F) = Power (P) / Velocity (V)

Substitute the given values: Power (P) = 2000 kW Velocity (V) = 20 m/s

Now, let's calculate the force of traction using the given values.

Calculation

Force of Traction (F) = 2000 kW / 20 m/s

F = 100 kN

So, the electric locomotive with a power of 2000 kW can develop a force of traction of 100 kN at a speed of 20 m/s.
