Certain springs are characterized by increasing stiffness with increasing deformation according to the relation F = k1x

Question:

Certain springs are characterized by increasing stiffness with increasing deformation according to the relation

F = k1x + k2x3 , where F is the force exerted by the spring, k1 and k2 are positive constants, and x is the

deflection of the spring measured from its undeformed position. Determine

(a) The potential energy Ve as a function of x,

(b) The maximum velocity of a particle of mass m attached to the spring and released from rest with x = x0 . Neglect friction.
