An object is dropped from a tower, 400400 ft above the ground. the object's height above ground x seconds after the fall is s(x)equals=400400minus−16xsquared2. about how long does it take the object to hit the ground? what is the object's velocity at the moment of impact?

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.
