Suppose a 51 kg bungee jumper steps off the Royal Gorge Bridge, in Colorado. The bridge is situated 321 m above the Arkansas River. The bungee cord's spring constant is 23 N/m, the
cord's relaxed length is 104 m, and its length is 179 m when the jumper stops falling. What is
the total potential energy associated with the jumper at the end of his fall? Assume that the
bungee cord has negligible mass.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
