What is the mass of a ball rolling at 5.00m/s if it has 3.00J of kinetic energy?

Explanation:

The equation for Kinetic Energy is

and we know everything but the mass of this ball. Filling in:

. Get everything isolated from the :

which tells us that we need 3 significant digits in our answer.

m = .240 kg since mass is always in kg i the velocity is in meters/sec

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 think it would be 5
