Solve the problem. PROVIDE THE GIVEN, REQUIRED, EQUATION, SOLUTION, AND FINAL ANSWER If the shock absorbers in a car go bad, then the car will oscillate at the least provocation, such as when going over bumps in the road and after stopping. Calculate the frequency and period of these oscillations for such a car if the car’s mass (including its load) is 786 kg and the force constant (k) of the suspension system is 5.78×104 N/m.
Near the top of the Citigroup Center building in New York City, there is an object with mass of 3.8 × 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. a)What effective force constant should the springs have to make them oscillate with a period of 1.4 s in N/m? b)What energy is stored in the springs for a 1.8 m displacement from equilibrium in J?
