A 2.74 kg object and changes velocity by 16.49 m/s in 16.19 s. How large of a force acted on the object? Which choice represents the best formula to calculate this answer?

real, smaller and upside-down.   so the answer should be b.

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.
