The given problem: m (the mass of the car in question) = 1 t (10 ^ 3 kg); V (travel speed) = 36 km / h (10 m / s).
We calculate the kinetic energy of the car under consideration by the formula: Ek = 0.5 * m * V2.
Calculation: Ek = 0.5 * 10 ^ 3 * 102 = 50 * 10 ^ 3 J (50 kJ).
Answer: The car in question has a kinetic energy of 50 kJ.
