answer both parts please

(7%) Problem 10: Near the top of the Citigroup Center building in New York City, there is an object with mass of 3.6 x 105 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.
