A spring of constant k and a damper of constant c are connected at one end to a body of mass m and the otherto a wall. The system rests on a horizontal frictionlesstable. An externalforce is applied to the system F,(t). Determine the position and velocity of the body with initial conditions x(0) = 0.2 m, v(0) = -1.5 m/s. We also know that m = k = 15N/m y F,(t) = 3 cos(3t). 3.5 kg , c = 1N s/m,
