Use Laplace's method to solve

A mass of 1 slug is attached to a spring whose constant is 5lb/ft. Initially, the mass is released 1 foot below the equilibriumposition with a downward velocity of 3 ft/s, and the subsequentmotion takes place in a medium that offers a damping force that isnumerically equal to 2 times the instantaneous velocity.

(a) Find the equation of motion if the mass is driven by anexternal force equal to f(t) = 8 cos 2t + 2 sin 2t

x(t) = ?

(b) Graph the transient and steady-state solutions on the samecoordinate axes.

(c) Graph the equation of motion.
