1 (a) In Figure Q1, the 25 kg mass (m) is suspended by a combination of springs, where ku=5 kN/m, kz=5 kN/m, k3=10 kN/m and k4=10 kN/m. The mass is displaced 30mm below the static equilibrium position and released from rest, determine: (i) The equivalent stiffness of the four springs. (ii) The undamped frequency of the equivalent system. (iii) The equation that governs the vertical displacement of the mass as a function of time. (iv) The maximum acceleration of the mass in mm/s?. (v) The location of the mass in mm at time, t = 2 s. que ki k2 k3 k4 Static equilibrium position m
