For the system shown below, what is the critical angle (angle at which the system just begins to move)? assume that the coefficient of friction between all flat surfaces is 0.0500 and that the pulley is frictionless. the mass of m1 is 76.00 kg and the mass of m2 is 194.00 kg. express your answer in radians.

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.
