Hanging Spring When a 0.30 kg mass is suspended from a massless spring, the spring stretches a
distance of 2.0 cm.
Let 2.0 cm be the rest position for the mass-spring system.
The mass is then pulled down an additional distance of 1.5 cm and released.

Calculate the total mechanical energy of the system in SI units.

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
