The correct answer is:
The 5-kilogram fish swimming at a speed of 10 meters/second has more momentum than the 2-kilogram fish swimming at the same speed.
Here's why:
1. Momentum is calculated by multiplying an object's mass by its velocity. Momentum = mass x velocity.
2. In this case, the momentum of the 5-kilogram fish is 5 kg x 10 m/s = 50 kg*m/s.
3. The momentum of the 2-kilogram fish is 2 kg x 10 m/s = 20 kg*m/s.
4. Therefore, the 5-kilogram fish has more momentum (50 kg*m/s) compared to the 2-kilogram fish (20 kg*m/s) when they both swim at a speed of 10 meters/second.
