Now a squirrel has very little mass and the spread of its body is comparatively large. Therefore, when it jumps down the tree, the drag force is larger. The squirrel comes down with a much lower velocity and remains undamaged. On the other hand, a man’s weight is much larger as compared to its spread or exposed area. Therefore, the drag force is also greater and he hits the ground with a greater velocity and gets his bones broken.
