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 hall has greater kinetic energy, and why?
A. the yellow ball has a greater kinetic energy, because it is rolling at a higher position above the ground.
B. the red ball has a greater kinetic energy, because it has a greater mass.
C. the yellow ball has greater kinetic energy, because it is rolling at a greater speed.
D. the red ball has greater kinetic energy, because it is releasing more thermal energy.
