Answer :
Final answer:
The question pertains to Physics, specifically on the topic of projectile motion with relevance to the time a ball would be in the air and the distance a football would travel before it lands. The time a ball would be in the air is determined by its vertical motion. The distance a football would travel, however, would need more context or information to be accurately determined.
Explanation:
The subject of this question falls under Physics. The questions are based on the topic of projectile motion which is a typical High School level physics topic. It appears the student is asking for the time a ball (object) will be in the air and the distance it will travel before it lands. These are characteristic questions when studying the physics of motion.
From the provided reference, the time for projectile motion is determined completely by the vertical motion. Therefore, any projectile such as a ball, that has an initial vertical velocity and lands to a different altitude, will spend a specific time in the air. For example, a projectile with an initial vertical velocity of 21.2 m/s landing 10m below its starting altitude will be in the air for 3.79 s, thus option d) 3.8 seconds could be the closest answer for how long a ball will be in the air.
For the second question, we do not have enough information or context to accurately calculate the distance the ball (football) would travel before it lands.
