"Автомобиль массой 4т обладает энергией 0.6 МДж. Чему равна скорость?"

Using the formula for kinetic energy, we can calculate the velocity of the car. The formula is:

E = (1/2)mv^2

Where: E = energy (0.6 MJ) m = mass (4 tonnes = 4000 kg) v = velocity

Rearranging the formula, we find:

v = √(2E/m)

Now let's substitute the values:

v = √(2 * 0.6 * 10^6 J / 4000 kg)

Calculating this, we get:

v ≈ 17.32 m/s

So, the velocity of the car is approximately 17.32 m/s.
