A second-order mechanical system is described by the differential equation: md^2x/dt^2 + bdx/dt + kx = f(t), with m = 2kg, b = 3Ns/m, k = 5N/m and with initial conditions x(0)=0, dx/dt(0)=0. Apply the Laplace Transform to derive the output response x(t) when f(t) = 10u(t).
💡 Hint: Consider the coefficients and transformations step-by-step carefully.
An electrical RLC circuit is characterized by the equation Ld^2i/dt^2 + Rdi/dt + (1/C)i = v(t). Given that L=0.5H, R=1Ω, and C=0.002F, with initial conditions i(0)=1A, di/dt(0)=0. Find the current response i(t) for a unit step input.
💡 Hint: Don’t forget to convert all coefficients to their proper forms in the Laplace domain.
