Two 1 kg balls move away from each other, one traveling 10 m/s to the right, the other 4 m/s to the left. What is the magnitude of the total momentum of the system

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba
