oggers, where does the increase in force come from? Surely your triangle of forces shows a decrease in the vertical impact and therefore must increase the horizontal force impact: i.e. the dry stone wall. Following the landing the drag from the surface will also form a part which will then absorb the energy further before eventually impacting with the wall, when all energy is then dissipated and comes to rest.
