The St. Louis Arch has a height of 192 m.

Suppose that a stunt woman of mass 96 kg

jumps off the top of the arch with an elastic

band attached to her feet. She reaches the

ground at zero speed.

The acceleration of gravity is 9.81 m/s^2.

Find her kinetic energy after 3.8 s of the

flight. Assume the elastic band has no length

and obeys Hooke’s Law.

Answer in units of kJ.
