A spring with a spring constant 4 N/m is loaded with a 2 kgmass and allowed to reach equilibrium. It is then displaced 1 meter downward and released. Suppose the mass experiences a damping force in Newtons equal to 1 times the velocity at every point and an external force of F(t)=4sin(3t) driving the system. Set up a differential equation that describes this system and find a particular solution to this non-homogeneous differential equation:

damping force in Newtons equal to 1 times the velocity

so damping constant is

external force is

DE is given by

....................differential equation for this system

in question mention that, find an only a particular solution

here we have so assume that particular solution is

....................(1)

put all values in DE

compare coefficient both sides

....................put both constants in equation 1

...................... particular solution
