Engineering Application Near the top of the Citigroup Center building in New York City, there is an object with mass of 4.00 × 10° kg on springs that have 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-the driving force is transferred to the object, which oscillates instead of the entire building. (a) What effective force constant should the springs have to make the object oscillate with a period of 2.00 s? (b) What energy is stored in the springs for a 2.00-m displacement from equilibrium?

Engineering Application
Near the top of the Citigroup Center building in New
York City, there is an object with mass of
4.00 x 10° kg on springs that have 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-the driving
force is transferred to the object, which oscillates
instead of the entire building. (a) What effective force
constant should the springs have to make the object
ocillate with a period of 2.00 s? (b) What energy is
stored in the springs for a 2.00-m displacement from
equilibrium?
