Two soccer balls are rolling across a field. Ball 1 has a mass of 1.0 kg, and ball 2 has a mass of 1.5 kg. Ball 1 is traveling at a speed of 4.0 m/s, and ball 2 is traveling at a speed of 5.0 m/s. What is the difference in kinetic energy between ball 1 and ball 2?
a.The kinetic energy is equal for both balls.
b.The kinetic energy of ball 1 is 8 J greater than ball 2.
c.The kinetic energy of ball 2 is 10.75 J greater than ball 1.
d.The kinetic energy of ball 2 is 18.75 J greater than ball 1.
