both will hit the ground at the same time. Explanation: If we neglect the effect air resistance and curvature of the earth then both pellets will hit the ground at the same time. The pellet dropped would depend on vertical velocity, while the pellet fired would have both horizontal and vertical velocities but since their potential energy (height, mass and gravity) is the same and the horizontal velocity wont affect the kinetic energy of the pellet fired therefore both will hit the ground at the same time.
