Answer: B. The red ball has greater kinetic energy, because it has a greater mass.
Explanation:
The factors influencing the kinetic energy of an object are its mass and its velocity. Both of the balls have the same velocity; however, the red ball has a greater mass. Therefore,
The red ball has greater kinetic energy, because it has a greater mass.
I hope this helps:)
The red ball has a greater kinetic energy because it has more mass. Kinetic energy’s equations is
K.E. = 1/2 • mass • velocity squared
They both have the same velocity, so whichever has the higher mass has more kinetic energy.
