A mass attached to a spring, set in a container of molasses (a thick liquid) acts like a damped simple harmonic oscillator. The mass is 16 kg. the spring has a spring constant of 64 N/m and the molasses provides a damping force of 64 N-s/m. (a) The system is (A) underdamped (B) overdamped (C) critically damped (b) A force of F(t) (in N) is applied to the mass. If the method of undetermined coefficients is used to find a particular solution, which of the following is the best choice as a trial solution? 2e-21 (c) Initially, at / = Os, our mass is moving at a speed of 3 m/s as it passes through its equilibrium position (x0m). If we are still under the force from part (b), at what positive time, in seconds, does it again pass through x= Om? (If it never does, type dne).
