If you throw a raw egg against a wall, you'll break it, but if you throw it with the same speed into a sagging sheet it won't break. why? 1. the sheet is much slicker than the wall. 2. the breaking egg causes a larger impact time, decreasing the force. 3. the impact time when the egg strikes a sagging sheet is long, so the impact force is small. 4. the velocity of the egg decreases faster in the sheet than on the wall.
