Dropping a mass directly over the North Pole raises questions about its trajectory due to the Earth's motion. If the mass is released from a height of 6 km, it would initially share the Earth's orbital velocity, but as it falls, it must account for the Earth's movement beneath it. The Coriolis effect is negligible at the poles, but the mass will still experience gravitational influences from the Sun and Moon, which could alter its path slightly. The mass would not land directly on the North Pole unless it has a higher horizontal velocity component to match the Earth's orbit. Overall, the dynamics of the fall involve complex interactions between gravitational forces and the Earth's motion.
