1. The problem statement, all variables and given/known data 5. A sea hawk flying horizontally at a speed of 15 m/s drops a shellfish from a height of 30 m. At what speed does the shellfish hit the ground? Neglect air resistance (drag). 2. Relevant equations vf2 = vi2 + 2ah 3. The attempt at a solution I got 24.3 which was one of the answers and when i emailed the professor he said that that was the vertical velocity and I need to look for total velocity...well the answer is 28.5 m/s and I don't understand how that was arrived.
