Starting from a location with position vector r1,x =−17.5 m and r1,y=23.1 m , a rabbit hops around for 10.7 seconds with average velocity vav, x=−2.25 m/s and vav, y=1.79 m/s . Find the components of the position vector of the rabbit's final location, r2,x and r2,y .

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.

because if the tool that you are using is not balanced it there would be false mass.
