A 75 kg bungee jumper jumps off with zero initial speed from a high cliff with a bungee cord tied to her ankle. At some time dur
ing the jump, the bungee cord starts stretching. The lowest point in her jump where the bungee cord is at maximum stretch is a total drop of 195 m . What is the elastic potential energy stored in the bungee cord at the instant she reaches this lowest point?
I would say letter A to this because we need rain water for crops plants. Also we need it so that we can drink it. Its less great over sea because as it merge with the salt in the ocean it becomes less drinkable and less usable.
I believe Mercury has the most extreme temperatures in the solar system, ranging from -280?F at night to 800 degrees F during the day for parts of the surface.
