A bear and you are pulling in opposite directions on a picnic basket with a mass of 10 kg. The basket moves with constant velocity towards the bear, who pulls with 180 N. If the coefficient of friction is 0.5, how hard are you pulling? Draw the free body diagram and net force equations, and calculate all forces.

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.
