 182 = 0.005. See equations (3.5.1) and (3.5.2), 



we note that the equation of motion and initial conditions are identical 

 with (3.2.17) except that for the acceleration ^2 we use the damped sinusoid, 

 equation (2.5.5), instead of the half-sine pulse (3.2.1). The solution of 

 (3.2.17), i.e. the relative displacement (xi — x^) of nii with respect to tn^ , 

 is
