The automobiles have different masses and velocities. The drivers step on the brakes and all automobiles are brought to rest Part A Rank these automobiles based on the magnitude of their momentum before the brakes are applied, from largest to smallest Rank from largest to smallest. To rank items as equivalent, overlap them. If the ranking cannot be determined, check the box below.

Explanation / Answer

PART A:

Automobile 1: 500kg, 20m/s p = 10 000 kg·m/s  
Automobile 2: 4000kg, 5m/s p = 20 000 kg·m/s
Automobile 3: 1000kg, 20m/s p = 20 000 kg·m/s
Automobile 4: 500kg, 10m/s p = 5 000 kg·m/s
Automobile 5: 1000kg, 10m/s p = 10 000 kg·m/s
Automobile 6: 2000kg, 5m/s p = 10 000 kg·m/s

2,3 (tied); 1, 5, 6 (tied); 4

PART B:

Automobile 1: 1000kg, 20m/s p = 20 000 kg·m/s  
Automobile 2: 4000kg, 5m/s p = 20 000 kg·m/s
Automobile 3: 1000kg, 10m/s p = 10 000 kg·m/s
Automobile 4: 500kg, 20m/s p = 10000 kg·m/s
Automobile 5: 500kg, 10m/s p = 5 000 kg·m/s
Automobile 6: 2000kg, 5m/s p = 10 000 kg·m/s

Impulse = change in momentum

1, 2 (tied); 3, 4, 6 (tied); 5
