1.2
Version 6B. Consider the initial value problem
x” +1.44 x = 1.28 (t – 172) + 1.28 (t – 1.7) + f(t), x(0) = 0, ‘(0) = 0,
where
1.2 if 37 0. Your expression may be
written in terms of unit step functions (Heaviside functions).
(b) Write the solution x(t) from part (a) as a simplified piecewise defined function, on the
intervals 0
