A clever engineer designs a "sprong" that obeys the force law Fx=−q(x−xe)3, where xe is the equilibrium position of the end of the sprong and q is the sprong constant. For simplicity, we'll let xe=0m. Then Fx=−qx3. Find an expression for the potential energy of a stretched or compressed sprong.

Because of your role in the 'Great Penguin Riot and Massacre of 2014,' you have been relegated to the slug pen. While attending to your many exciting responsibilities, you have had time to design a new thingamajig which you can call a sprong. After months of careful testing, you have determined that the spring obeys the force law F=-q (x-xe)^3î-q (y-ye)^3j where xe and ye are the equilibrium positions for the x-coordinate and ya coordinate, respectively. For simplicity, let xe=0...
Consider a mass m suspended from a massless spring that obeys Hooke's Law (i.e. the force required to stretch or compress it is proportional to the distance stretched/compressed). The kinetic energy T of the system is mv2/2, where v is the velocity of the mass, and the potential energy V of the system is kr-/2, where k is the spring constant and x is the displacement of the mass from its gravitational equilibrium position. Using Lagrange's equations for mechanics (with...
2. Consider the following physical situation: A spring that obeys Hooke's Law and has a known/given spring constant k has been compressed to half of its equilibrium length. It's anchored at one end while the other end pushes (but is not attached to) a block of mass m in the horizontal direction. The block is initially held in place. Once released, the block accelerates to the right and achieves a final speed of ve at the point when it leaves...
A spring of force constant 3 N/m is compressed by 5.0 em from its equilibrium position. The spring is then released and stretched by 5.0 ㎝ from its equilibrium position. Find the difference in potential energy between the two positions of the spring (stretched and compressed).

A spring is found to not obey Hooke's law. It exerts a restoring force F(x) =-ax- 2 N if it stretched or compressed, where α = 60 N/m and β 18.0 Nm2/3. The mass of the spring is negligible.
