A system of springs with effective stiffness of k 8045 Nm s

A system of springs with effective stiffness of k = 8045 N/m supports a mass m = 12.1 kg. The mass is displaced by 15 mm and released. Question 11 Determine the static deflection when the mass is attached to the spring. (a) 15.5 mm (b) 15.25 mm (c) 15 mm (d) 14.75 mm (e) 14.5 mm

Spring force = kx

F = 12.1*9.81
