A 50.0 g object moves on the end of a spring( with spring constant k = 25.0 N/m). it is released with an initial displacement of 0.300m A damping force F = -c(dx/dt) acts on the object. After it oscillates for 5.0 s, the displacement of the object is 0.100m. From the hints provided it is an Underdamed System. Calculate c, the magnitude of the damping coefficient.
