You are trapped on the second floor of a burning building. The stairway is impassable, but there is a balcony outside your window. Describe what might happen in the following situations.
(a) You jump from the second story balcony to the pavement below, landing stiff legged on your feet.
(b) You jump into a privet hedge, landing on your back and rolling to your feet.
(c) You jump into a firefighters' net, landing on your back. What happens to the net as you land in it? What do the firefighters do to cushion your fall even more?
