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
