Question

M=3кг V=30м/с V=10м/с P-?

Answer 1

P=m(v1-v2)=3*(30-10)=60

Answer 2

To calculate the power (P) using the given values of mass (M) and velocity (V), you can use the formula:

P = (1/2) * M * (V^2)

Plugging in the values:

P = (1/2) * 3 kg * (30 m/s)^2

P = (1/2) * 3 kg * 900 m^2/s^2

P = 1,350 joules per second (or watts)

Therefore, the power (P) is 1,350 watts.
