What principle is applied to determine the total momentum of the system before and after a bomb splits into fragments?

1. The expression 50 - (400 × 25) / 1000 + (600 × v) / 1000 is used.
2. The velocity of the fragment is calculated as 100 m/s in the upward direction.
3. The momentum of the bomb is calculated as 1 × 50 = 50.
4. The law of conservation of momentum states that the total momentum before and after the split remains the same.

Correct answer: The law of conservation of momentum states that the total momentum before and after the split remains the same.

Solution

The question emphasizes the principle of conservation of momentum, which states that the total momentum before splitting equals the total momentum after splitting. This is the key concept being tested.
