Final answer:
The question relates to calculating the horizontal distance of a horizontally thrown ball from a building before hitting the ground. The solution involves finding the time the ball is in the air based on vertical fall and then multiplying by the horizontal velocity, which is not provided in the question.
Step-by-step explanation:
The subject of this question is Physics, and it pertains to projectile motion in the High School grade level. To solve for the horizontal distance traveled by the ball before hitting the ground, we need to calculate the time the ball takes to fall from a height of 45.0 m. However, the given reference information does not include the initial horizontal velocity for this scenario.
Instead, we can use the example of a ball thrown from a 60.0-m building landing 100.0 m away to understand the concept. From this, we know we'd first calculate the time it takes for the ball to fall, and then use this time along with the initial horizontal velocity to determine how far it traveled horizontally. For a 45.0 m fall, once we find the time, the initial horizontal velocity (which must be provided or calculated from another part of the problem) would be multiplied by this time to find the horizontal distance.
