To find out the required kinetic energy of the presented car, consider the formula: Ek = 0.5 * ma * V ^ 2.
Data: ma – vehicle weight (ma = 103 kg); V – constant speed (V = 10 m / s).
Calculation: Ek = 0.5 * ma * V ^ 2 = 0.5 * 10 ^ 3 * 10 ^ 2 = 5 * 10 ^ 4 J.
Answer: The kinetic energy of the presented car should be 50 kJ.
