A 3 kg mass is held against spring compressed horizontally by 0.5 m. If the spring constant is 145 N/m how much energy is stored in the spring? What is the velocity of the mass when pushed by the spring? How far will the mass slide on the surface if the coefficient of kinetic friction on the surface is 0.25?

he . if i may ask what i your question exactly?

explanation:

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.

overcharge is the right answer system
