Find the solution to the initial value problem. z''(x) + z(x) =2e-OX; z(0) = 0, z'(0) = 0 2 12 2 The solution is z(x) = 37 COS X + 37 sin x + 6x 371 5 A E-kg mass is attached to a spring with stiffness 52 N/m. The damping constant for the system is 4 N-sec/m. If the mass is moved M to the left of equilibrium and 26 given an initial leftward velocity of 3 m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency. What is the equation of motion? y(t)= (Type an exact answer, using radicals as needed.) The damping factor is The quasiperiod is seconds. The quasifrequency is Hz
