Analyzing Kinetic energy
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?
O The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground.
O The red ball has greater kinetic energy, because it has a greater mass.
O The yellow ball has greater kinetic energy, because it is rolling at a greater speed.
O The red ball has greater kinetic energy, because it is releasing more thermal energy.

Answer 1

Force = Mass * Acceleration therefore the red ball with the higher mass will have more force and greater acceleration
