SUMMARY
The problem involves calculating the total velocity of a shellfish dropped from a height of 30 meters by a sea hawk flying at 15 m/s. The vertical velocity upon impact is calculated using the equation vf² = vi² + 2ah, resulting in a vertical velocity of 24.3 m/s. To find the total velocity, the horizontal velocity of 15 m/s is combined with the vertical velocity using the Pythagorean theorem, yielding a total impact velocity of 28.5 m/s. Air resistance is neglected in this scenario.
