Extracted text: A mass of 1 slug is attached to a spring whose constant is 5 Ib/ft. Initially, the mass is released 1 foot below the equilibrium position with a downward velocity of 7 ft/s, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 2 times the instantaneous velocity. (a) Assume the mass is driven by an external force equal to f(t) = 16 cos(2t) + 4 sin(2t). Find the initial conditions. x(0) ft %3D x'(0) = ft/s Find the particular solution. ft Xp = Find the equation of motion of the mass. x(t) = ft
