A spring with a mass of 2 kg has damping constant 12, and a force of 8.75 N is required to keep the spring stretched 0.5 m beyond its natural length. The spring is stretched 2 m beyond its natural length and then released with zero velocity. Find the position of the mass at any time t. x(t) = A series circuit contains a resistor with R = 120 Ohm, an inductor with L = 10 H, a capacitor with C = 0.001 F, and a 12 V battery. The initial charge is Q = 0.002 C and the initial current is 0. Find the charge and current at time t. Q(t) = I(t) =
