Question: A spring-rn ass system, m and k, is started with an initial displacement of unity and an initial veIocity of zero. Plot In X versus n, where X is the amplitude at cycIe n for
(a) viscous damping with ζ = 0.05, and
(b) Coulomb damping with damping force Fd = 0.05k. When will the two amplitudes be equal?
