Question: Near the top of the Citigroup Bank building in New York City, there is a 4.00 105 kg mass on springs having adjustable force constants. Its function is to dampen wind-driven oscillations of the building by oscillating at the same frequency as the building is being driven â€" the driving force is transferred to the mass, which oscillates instead of the building.

(a) What effective force constant should the springs have to make the mass oscillate with a period of 5.00 s? N/m

(b) What energy is stored in the springs for a 1.00 m displacement from equilibrium? J
