(20pts)
An undamped single-degree-of-freedom system consists of a mass 5 kg and a spring of stiffness
1000Nm. Find the response of the system using x(t)=Acos(nt-) when the mass is
subjected to the following initial conditions:
a.x0=10mm,x0=100mms
b.x0=10mm,x0=-100mms
( 2 0 p t s ) An undamped single - degree - of -
