The best prediction is:
**The ball hit at 80 miles per hour will have more kinetic energy.**
Kinetic energy can be calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \( KE \) is kinetic energy, \( m \) is mass, and \( v \) is velocity. Since the mass of both balls is the same, the kinetic energy will be directly influenced by the square of the speed. The ball hit at 80 miles per hour will have a higher kinetic energy compared to the one hit at 78 miles per hour.
