A linear spring-mass system (without friction) satisfies m(d^2x/dt^2) = -kx, Derive that m/2 (dx/dt)^2 + k/2 x^2 = constant = E. Consider the initial value problem such that at t = 0, = x_0 and dx/dt = v_0. Evaluate E. Using the expression for conservation of energy, evaluate the maximum displacement of the mass from its equilibrium position. Compare this to the result obtained from the exact explicit solution.

A particle of mass m slides without slipping down and inclined plane of mass M. The plane(a triangle) in turn can slide along the horizontal surface without friction. Find the Lagrangian in terms of (x, s, dx/dt, ds/dt), where s is the distance the particle has traveled down the incline, and solve the corresponding Euler-Lagrangian equations. Let x(t) be the location of the block, relative to the fixed origin, and x(0) = dx/dt(0) = 0, as well as s(0) =...
