The potential energy of a conservative force is U(x) = ax?-bx", with a and b positive constant parameters. (a) Find the equilibrium points and discuss whether these points are stable or unstable (and why). (b) At time t=0, a particle with mass m and initial velocity vin=0 is placed at a distance xin close to the stable equilibrium point. Assume that xXin is very small compared with the distance between the stable and the unstable equilibrium points. Find an approximate expression for the period of oscillations of the mass m. (c) A second particle with mass M is placed, at time t=0, at the exact position of the stable equilibrium point, with a non-zero initial velocity vin. Find the minimum value of vin such that the particle can travel a distance at least equal to the distance between the stable equilibrium point and the nearest unstable equilibrium point. This problem must be solved symbolically, numbers are not required.

3. Let's imagine that the earth is shrinking and we want to escape before it is too late. Let's set up some notation: R: the radius of Earth MẸ : the mass of Earth m: your mass G : the universal gravitational constant c: the speed of light Note that, since Earth is shrinking, R is not constant, but MẸ is constant (the values of ME, G and c are available on Wikipedia). In this question, we will compute the velocity needed to escape Earth and the radius of (shrunken) Earth for which even light cannot escape (when Earth becomes a black hole). In fact, all of the related formulae are well known and the purpose of this question is to justify our work using what we have learned in this course so far. (a) The work (energy) W needed to free yourself from Earth when its radius is R metres is w = G ME m dh. h2 R Show that this improper integral is equal to GME m R
