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 both balls have the same mass, the ball hit at a higher velocity (80 miles per hour) will have greater kinetic energy than the one hit at 78 miles per hour.
**The ball hit at 80 miles per hour will have more kinetic energy.**
