A particle is restricted to move without friction in a circular wire of radius R that rotates with constant angular speed \omega around its vertical diameter (figure opposite). Consider the acceleration of gravity g pointing downwards. a) Write the Lagrangian for that particle (already replacing the links). How many degrees of freedom does she have? b) Find the equation of motion and the equilibrium angles $\theta_0$ for that particle. How many balancing positions are there? c) Consider small displacements around the equilibrium angles ($\theta = \theta_0 + \epsilon$), and find the equations in first order for $\epsilon$. Under what conditions are the equilibrium points stable or unstable? What are the frequencies of small oscillations around the stable equilibrium points?

Let x(t) be the displacement from equilibrium of a mass attached to a spring, satisfying the differential equation\\ $\frac{d^2x}{dt^2} + 4\frac{dx}{dt} + 4x = 0$, $x(0) = 1$, $x'(0) = v_0$.\\Here $v_0$ is a constant, giving the initial velocity of the mass.\ a) Find a formula for the displacement x(t) in terms of t and $v_0$.\ b) For what range of $v_0$ does the mass pass through the equilibrium point at some time t > 0?
