A spring-mass system consists of a spring of stiffness 20 N/mm and a mass 12.74 kg, which can slide on a dry horizontal plane surface with a coefficient of friction 0.32. The mass has displaced a distance 39 mm to the right of the frictionless equilibrium position and then released with zero initial velocity. Determine: a) The frequency of vibration. b) The position and time at which the mass stops.
