A pitching machine is used to pitch two balls. The velocity of both balls is 94 km/hr.

The mass of one ball is 5 grams, and the mass of the other ball is 50 grams. Since both balls are traveling at the same velocity, which of the following is true?

• Neither ball has any kinetic energy.

• The 5-gram ball has more kinetic energy than the 50-gram ball.

• The balls have the same kinetic energy.

• The 50-gram ball has more kinetic energy than the 5-gram ball.
