The best prediction is: **The ball hit at 80 miles per hour will have more kinetic energy.**
Kinetic energy is calculated using the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass of the object and \( v \) is its velocity. Since the mass of both balls is the same, the kinetic energy will depend on the square of their velocities. The ball hit at 80 miles per hour has a higher speed, and thus will have more kinetic energy than the ball hit at 78 miles per hour.
