Math Problem Statement
Ajoneuvon massa on 2365 kg ja sen nopeus on 104 km/h. Ajoneuvoa jarrutetaan tasaisella tiella, jossa kitkanomtien ja renkaiden välillä on 0.43. Jos kaikki neljä pyoraa jarruttavat, mikä on auton pysähtymisen aikana kulkema matka? Anna vastaus kokonaislukujen tarkkuudella. Putoamiskiihtyvyys on 9.81 m/s²
