A 1-kilogram mass is attached to a spring whose constant is 24(N)/(m), and the entire system is then submerged in a liquid
that imparts a damping force numerically equal to 11 times the instantaneous velocity. Determine the equations of motion
if the following is true.
(a) the mass is initially released from rest from a point 1 meter below the equilibrium position
(b) the mass is initially released from a point 1 meter below the equilibrium position with an upward velocity of
13(m)/(s)

DEFINITION 7.1.1 Laplace Transform
Let f be a function defined for t>=0. Then the integral
L{f(t)}=int_0^(infty ) e^(-st)f(t)dt
is said to be the Laplace transform of f, provided that the integral converges.
Find /_(f(t)) - (Write your answer as a function of s.)
