A yellow ball with a mass of 2 kg is rolling across the floor at 3 m's A red ball with a mass of 3 kg is rolling across the

same floor at 3 m's Which ball has greater kinetic energy, and why?

The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground

The red ball has greater kinetic energy, because it has a greater mass

The yellow ball has greater kinetic energy, because it is rolling at a greater speed

The red ball has greater kinetic energy, because it is releasing more thermal energy

    The red ball has a greater kinetic energy, because it has a greater mass

    Explanation:

    Mass is directly proportional to kinetic energy, as one increases, so does the other

    The red ball has greater kinetic energy, because it has a greater mass

    Explanation:

    just look at the formula : K. E. = 1/2 m v (^2) (the ^2 is an exponent.)
