Air resistance is negligible a reasonable assumption in this scenario?
Into account the situation of hiking in the mountains and launch a compass for his friend. The friend lost the compass and falls into a precipice of 400 meters (more than the height of the Empire State Building). Suppose that the compass is momentarily Resting on top of its path of travel and all out (horizontal) motion is important for its calculations. In addition, for the sake of simplifying calculations assume that the wind is calm and the air resistance is negligible. Note that the standard SI unit for force is the Newton (N), and is equivalent to kg * m / s / s.
No, it is not. But you can not fight the hypothetical.
