Homework Statement
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)
Homework Equations
F=-k(dx)
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.
