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.

In order to determine which ball has a higher kinetic energy, we first look at the formula of kinetic energy which is:
kinetic energy = 1/2 * mass * velocity²

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.
We may also determine these quantitatively using the formula given and the kinetic energy of the yellow ball works out to be 9 J and that of the red ball is 13.5 J.

The red ball has greater kinetic energy, because it has a greater mass. Option B is correct.

The formula of kinetic energy which is:

[tex]\bold {KE = \dfrac 1 {2} mv^2}[/tex]

Where,

m - mass

v - velocity

The kinetic energy of the object depends upon its mass and velocity.

The kinetic energy of yellow ball

[tex]\bold {KE = \dfrac 1 {2} 2\times 3^2 = 9 J}[/tex]

The kinetic energy of red ball

[tex]\bold {KE = \dfrac 1 {2} 3\times 3^2 = 13.5 J}[/tex]

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