Question

автомобиль массой 3 000 кг движется со скоростью 10 м\с . Чему равна его кинетическая энергия?

Answer 1

Eк.=mv^2/2

Eк.=3000кг*(10м/с)^2/2

Ек.=150000

Answer 2

Кинетическая энергия тела расчитывается по формуле:

Ek=mv^2/2

Ek=3000*100/2=150000Дж=150кДж

Ответ:150кДж

 

Answer 3

Calculation of Kinetic Energy

To calculate the kinetic energy of an object, we can use the formula:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

Given that the mass of the car is 3,000 kg and its velocity is 10 m/s, we can substitute these values into the formula to find the kinetic energy.

KE = 0.5 * 3,000 kg * (10 m/s)^2

Calculating this equation, we find that the kinetic energy of the car is 150,000 Joules (J).

Therefore, the kinetic energy of the car is 150,000 Joules.
