Answer:
Ranks based on momentum are
1. 1200 kg car going at 15 m/s.
2. 15 kg meteor going at a speed of 100 m/s.
3. 100 kg person running at 5 m/s.
4. 10000 kg train car at rest.
Step-by-step explanation:
Product of a body’s mass and velocity gives the value of its momentum. It is given by the equation

where is the mass of the object and is the velocity.
Calculating the values of momentum:
1. mass= 1200 kg, velocity= 15 m/s

2. mass= 15 kg, velocity= 1000 m/s

3. mass= 100 kg, velocity= 5 m/s

4. mass= 1000 kg, velocity= 0 m/s
