How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?

• The kinetic energy does not depend on the mass of the bowling ball.

• The kinetic energy is increasing proportional to the mass of the bowling ball.

• The kinetic energy is decreasing proportional to the mass of the bowling ball.

• The kinetic energy is increasing proportional to the square of the mass of the bowling ball.
