Answer 1

The ball hit at 80 miles per hour will have more kinetic energy.

Answer 2

The best prediction is that the ball hit at 80 miles per hour will have more kinetic energy.

Answer 3

To determine which ball will have more kinetic energy, we need to understand the relationship between kinetic energy and velocity.

The formula for kinetic energy is given by:

Kinetic Energy = (1/2) * mass * velocity^2

In this case, the mass of the balls is not mentioned, so we can assume it remains constant for both balls.

Now let's analyze the options given:

1. "The balls’ kinetic energies will depend on the distances they travel."
This statement is incorrect. The kinetic energy of an object depends only on its velocity, and not on the distance it travels. So, we can eliminate this option.

2. "The ball hit at 80 miles per hour will have more kinetic energy."
This statement is likely to be correct since the ball hit at a higher velocity will have more kinetic energy. We can keep this as a potential answer.

3. "The ball hit at 78 miles per hour will have more kinetic energy."
This statement is likely to be incorrect since the ball hit at a lower velocity will have less kinetic energy. We can eliminate this option.

4. "The balls will have the same amount of kinetic energy."
This statement is also incorrect, as mentioned earlier. The kinetic energy depends on the velocity, and since the velocities are different (78 mph vs. 80 mph), the balls will not have the same kinetic energy. We can eliminate this option.

Based on the analysis, the best prediction is that the ball hit at 80 miles per hour will have more kinetic energy.
