Task data: m (mass of the selected body) = 2 kg; V (speed of movement) = 18 km / h (in SI V = 5 m / s).

To calculate the kinetic energy of the selected body, we will use the formula: Ek = 0.5 * m * V ^ 2.

Let’s calculate: Ek = 0.5 * 2 * 5 ^ 2 = 25 J.

Answer: The kinetic energy of the selected body is 25 J.
