and released from that position, determine the maximum deflection xm of the spring and the maximum force Fm exerted by the spring, assuming(a) a linear spring of constant k = 3 kN/m, (b) a nonlinear spring, for which F= (3 kN/m)(x +160 x²).Note: May need numerical methods or trial-and-error for some steps.
