2) An undamped one-degree-of-freedom system has a mass coefficient of 50-kg and a natural frequency of 80 Hz. At t=0 s it is released from q(t=0)=20 mm with à (t=0)=-50 m/s. (a) Determine the maximum positive value of q that occurs in the ensuing vibration, and the earliest instant at which it occurs. (b) Determine the maximum positive value of q that occurs in the ensuing vibration, and the earliest instant at which it occurs.
