Bungy jump
A 58.0 kg bungy-jumper hangs suspended from her bungy-cord, at rest. She is displaced from this position by 11.00 m downward, and then released. She bounces up and down, with a period of 5.00 s. Assume the woman undergoes simple harmonic motion, described by
y(t) = X cos(2 ? t / T + ?)
Assume the mass of the bungy cord is negligible.
-the force (spring) constant k of the bungy cord is 91.6 N/m
and 5540J of energy was required to displace the woman from her rest position
a) When the woman is 4.00 m above her initial rest position and moving upwards,
What is her velocity?
