A particle of mass m undergoes one-dimensional undamped harmonic oscillation due to a restoring force Fr = -kx. In addition the particle is subject to a constant external force Fext = Fo.
a) What is the differential equation that governs the motion of the particle?
b) what is the general solution for the position of the particle as a fxn of t?
c) What is the motion of the particle in the limit t - > infinity
d) If the oscillations are damped, what would be the motion of the particle in the limit t-> infinit?
a) d^2x/d^t^2 + kx/m = Fo/m
b) After applying the method of undetermined coefficients
x(t) = Acos(Wot + phi) + Fo/k
c) V = -Asin(Wot+ phi)(Wo)
t-> infiity , v - inifity?
d) If the former was undamped, how does introducing the damping constant change my solution?
Thanks
