A 60 kg astronaut hovering in an orbiting space station throws a 1.0 kg water bottle (that he is holding) across the room at a speed of 8.0 m/s. What is the magnitude and direction
of the astronaut's velocity after he throws it?

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

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
