Final answer:
The physics question pertains to finding the time of flight for a baseball thrown from a 22.0 m tall building, which is calculated using the kinematic equations and is approximately 2.12 seconds.
Step-by-step explanation:
The subject of the question is Physics, as it involves concepts such as projectile motion, velocity, and time of flight which are a part of mechanics, a core area of physics. This problem falls under the domain of kinematics, which studies the motion of objects without considering the causes of motion.
The question specifically appears to seek assistance with part a) Find the time of flight. To determine the time of flight for a baseball thrown from a building, we would typically use the kinematic equations for uniformly accelerated motion. Assuming the only acceleration is due to gravity and neglecting air resistance, the time of flight can be calculated using the equation:
t = √(2h/g)
where t is the time of flight, h is the height of the building, and g is the acceleration due to gravity (9.8 m/s²). Substituting the given height of 22.0 m, we get:
t = √(2*22.0 m / 9.8 m/s²) = √(4.49 s²) ≈ 2.12 s
Therefore, the time of flight for the baseball would be approximately 2.12 seconds. This can help answer other questions, such as determining horizontal velocity or initial speed, but more information would be necessary to calculate those values.
