A weight attached to a 525N/m spring is a damped system. When the weight is displaced and left free, the resulting damped vibration period is 1.80s and at 2 amplitudes consecutive ones go from 4.2cm to 1.0cm. Determine the amplitude when the force F=2cos3t acts on the system. For logarithmic decrement use the full logarithmic decrement formula and remember the relationship between D static and D dynamic. 8= 2ηπξ √1-² D ** 1 2 2 1-B²) ² + (2. 5. B ²² =D dynamic /D static
