A70.0 kg stuntman is attached to a bungee cord with an unstretched length of 15.0 m. he jumps off a bridge spanning a river from a height of 50.0 m. when he finally stops, the cord has a stretched length of 44.0 m. treat the stuntman as a point mass, and disregard the weight of the bungee cord. assuming the spring constant of the bungee cord is 71.8 n/m, what is the total potential energy relative to the water when the man stops falling?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
