A person jumps odd the top of a building which is 12 metresabove ground. She is attached to the end of the bungie cord (a bigrubber band) that has an unstretched length of 6 metres. The cordstretches until the physics major is stopped 2 metres above theground. She then bounces back upward and begins oscillating(bouncing up and down). The student's mass is 55kg. Ignore airresistance. a) what is student's total energy after oscillationsbegin? b) what is spring constant k for bungie cord? c) what isfrequency of her oscillation? d) how long does it take her totravel up and down 4 times ( how long does it take her to complete4 oscillation)? e) what is the amplitude of resulting oscillation?f) what is her maximum speed after the oscillation begins?
