1. The problem statement, all variables and given/known data If a delicate istrument havng a mas of 5 kg is placed on a springof length L so tha its base just touches the undeformed spring and then inadvertly released from the position, determine the maximum deflection xm of the spring assuming (a) linear spring constant k=3000N/m (b) a hard, nonlinear spring, for which F=3000N/m(x+160x3) 2. Relevant equations F=-k(dx) 3. The attempt at a solution 5*9.81/3000=16.35 mm this is half of the answer why is that? Also can someone point me in te right direction for the nonlinear spring, that would be great.
