The engineer determines that the machine increased at a constant rate the disk’s angular speed from 100 rad/s to 300 rad/s over a time of 5 seconds. what was the angular displacement of the disk during those 5 seconds?

The disk's average angular speed during those 5 seconds was

(1/2) (100 + 300) rad/s = 200 rad/sec

Spinning for 5 sec at an average angular speed of 200 rad/s, the disk turned

(200 rad/s) x (5 s)  =  1,000 radians

(That's 500/pi revolutions = roughly 159.2 revolutions.)

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.

force tends to be low and long diustance masses are high
