5. problem 6.2
6. problem 6.7

Also, find the equilibrium points and the frequency for small oscillations around the equilibrium point for a y=x^4/a^3 shaped wire, which spins (around the y-axis at a rate Omega) in gravity (U=mgh)...

Plot things to illustrate your result.


4 a)For an oscillator box that slams into a wall and sticks after sliding toward the wall at a velocity v_0, calculate and plot x(t).

What if the box is allowed to bounce back? (and energy is conserved). How much energy goes into the internal oscillation.
What fraction of the total energy is that?

What fraction of the total energy was lost in part a??

Is this useful for understanding inelastic collisions??
