Free Mechanical Vibrations: Problem 5 (1 point) This problem is an example of over-damped harmonic motion. A mass m5 kg is attached to both a spring with spring constant - 160 N/m and a dash-pot with damping constant e60 N-s/m. The ball is started in motion with initial position o-2 m and initial velocity to 3 m/s Determine the position function z(t) in meters. Graph the function a(t).
