Question

Самолет массой 5000 кг летит со скоростью 300 м/с. Чему равна его кинетическая энергия:

Answer 1

По той же формуле..Ek=mv^2/2=225000000Дж=225МДж

Answer 2

Calculation of Kinetic Energy

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

Kinetic Energy (KE) = (1/2) * mass * velocity^2

Given that the mass of the airplane is 5000 kg and its velocity is 300 m/s, we can substitute these values into the formula to find the kinetic energy:

KE = (1/2) * 5000 kg * (300 m/s)^2

Let's calculate the result:

KE = (1/2) * 5000 kg * (300 m/s)^2 = 225,000,000 Joules

Therefore, the kinetic energy of the airplane is 225,000,000 Joules.
