Acar accelerates from rest at -2.40 m/s2. (include the sign in your answers.) (a) what is the velocity at the end of 3.6 s?

Explanation:

We have equation of motion v = u + at

     Initial velocity, u  0 m/s

     Final velocity, v = ?  

     Time, t = 3.6 s

      Acceleration, a = -2.40 m/s²

     Substituting

                      v = u + at  

                      v = 0 + -2.40 x 3.6

                      v = -8.64 m/s

Velocity at the end of 3.6 s is -8.64 m/s

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.
