Question
8. Car A has a mass of 1000 kg and a speed of 30m/s. Car B has a mass of 3000 kg and a speed 10m/s The momentum of car A has __ car B. (1 Point) less momentum than more momentum than the same momentum as 9. If a 1000-kg car has a speed of 30m/s its momentum is (1 Point) [4 450,000kg^ast m/s 30,000kg^ast m/s 33.3kg^ast m/s 30,000N/s

Answer
8. **The same momentum as**<br /><br />Here's why:<br /><br />* **Momentum (p) is calculated as mass (m) times velocity (v):** p = m*v<br /><br />* **Car A:** p = (1000 kg) * (30 m/s) = 30,000 kg*m/s<br />* **Car B:** p = (3000 kg) * (10 m/s) = 30,000 kg*m/s<br /><br />Both cars have the same momentum.<br /><br /><br />9. **30,000 kg*m/s**<br /><br />As explained above, momentum is calculated as mass times velocity:<br /><br />p = (1000 kg) * (30 m/s) = 30,000 kg*m/s<br />
