Problem 1:
A mass of 20 grams stretches a spring by 10/169 meters.
(a) Find the spring constant k, the angular frequency w, as well as the
period T and frequency f of free undamped motion for this spring-mass
system.
(b) Find the general solution x(t) of the DE for the free spring-mass
system.
(c) Suppose that an exterior force of
F(t) = 2.5 sin(12t) in Newtons
acts on the spring-mass system. Find the equation of motion (the solution
x(t)) of the system if the mass initially is at rest in its equilibrium position.
