8) As a spring is heated, its spring constant decreases. Suppose that this decrease of the constant follows the equation k(t) = 6-t N/m. Write the ODE for the Mass/Spring system (IVP) and find the first four non-zero terms of the Power Series Solution about t = 0. k(t)=6-1 N/m 1 N-sec/m 2 kg x(t) x(0)=3m x'(0) = 0 m/sec
