Final answer:
The question pertains to the Physics subject, focusing on circular and projectile motion principles. The problem requires understanding constant horizontal velocity and gravitational acceleration to calculate the final velocity of a falling object.
Step-by-step explanation:
The student's question is related to Physics, specifically to the topic of circular motion and projectile motion. The hawk's flying motion can be associated with uniform circular motion, where various physical quantities such as centripetal force, centripetal acceleration, and angular velocity might be investigated.
To address the example given for the eagle and the fish, we need to calculate the velocity of the fish relative to the water when it hits the water. The eagle's horizontal velocity and the acceleration due to gravity will determine the final velocity of the fish. The horizontal component of the velocity remains constant at 3.00 m/s, while the vertical component increases due to acceleration caused by gravity (9.81 m/s2). We would use kinematic equations to find the time taken to fall 5.00 m and hence the vertical component of velocity.
The final velocity would then be found using the Pythagorean theorem, combining the constant horizontal velocity and the calculated vertical velocity at the moment the fish hits the water.
