If an object with a mass of 30 kg accelerates at a rate of 2 m/s^2, what is the magnitude of the force acting it?

Hello, for this use the second law of Newton:

F = ma

We have the data:

F = ?

m = 30 kg

a = 2 m/s^2

Replacing:

F = 30 kg * 2 m/s^2

F = 60 N

Result:

The force is of 60 Newtons.

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.

i'm on my way to history not a mistory.
