Question

M =1,4т V =20 м/с P-?

Answer 1

P=m : V

1,4 : 20 =0,07

Answer 2

To calculate the power (P), we can use the formula:

P = M * V

Where: P is the power M is the mass V is the velocity

Given: M = 1.4 t (tonnes) = 1,400 kg (since 1 tonne = 1,000 kg) V = 20 m/s

Let's substitute the given values into the formula:

P = 1,400 kg * 20 m/s P = 28,000 kg⋅m/s

The unit of power is the watt (W), which is equivalent to 1 kg⋅m²/s³. To convert the result to watts, we divide by the conversion factor:

P = 28,000 kg⋅m/s / (1 kg⋅m²/s³) P ≈ 28,000 W

Therefore, the power (P) is approximately 28,000 watts.
