A toy car of mass m is attached to one end of a light horizontal spring, fixed to a rigid support. The toy car is so arranged to move on a frictionless surface. The spring is pulled and released, compelling the toy car to be moving back and forth simple harmonically in a horizontal plane. Which of these actions would increase the frequency of the oscillations of the toy car?

Near the top of the Citigroup Center building in New York City, there is an object with mass of 4.00105 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.
