Task data: m (mass of a given vehicle) = 2 t (in SI m = 2000 kg); V (travel speed) = 54 km / h (in SI V = 15 m / s).
To determine the kinetic energy of a given car, we use the formula: Ek = m * V2 / 2.
Let’s calculate: Ek = 2000 * 152/2 = 225 * 10 ^ 3 J (225 kJ).
Answer: The given vehicle had a kinetic energy of 225 kJ.
