97. Girya mass m = 0,5 kg, suspended by the helical spring stiffness k = 50 N / m, oscillates in a viscous medium with a resistance coefficient r = 0,5 kg / s. At the upper end of the spring effect the driving force that varies according to the law F = 0,1cosωt, N. Determine for the oscillating system: 1) the damping coefficient δ; 2) the resonant amplitude Arez.
