Consider two particles m1 and m2. Let mlbe confined to move on a circle of radius R1
in the z-0 plane and centered at x-0, y-0. Let m2 be confined to move on a circle of
radius R2 in the z-a plane and centered at x-0, y-0. A massless spring of spring
constant C is joining the two particles.

Assume that you do not know about the kinetic energy or Newton’s Laws of motion. Suppose instead of deriving the Euler-Lagrange equations, we postulate them. We define the basic law of mechanics to be these equations and ask ourselves the question: What is the Lagrangian for a free particle? (This is a particle in empty space with no forces acting on it. Be sure to set up an inertial reference system.) The simplest choice might be to guess it must be proportional to v2,where v→ is the particle velocity in an inertial frame K. Take L = v2. A second inertial frame K′ moves at constant velocity −V0→ with respect to K, so that the transformation law of velocities isv'→ = v→ + V0→. Prove that L' = v'2 is a possible choice for the Lagrangian in the frame K′. Explain how this proves that all inertial frames are equivalent. With this approach we prove the equivalence of inertial frames from the form of the Lagrangian, instead of postulating this equivalence at the start, which is usual way…

Problem 3: A mass m is thrown from the origin att = 0 with initial three-momentum po in the y direction. If it is subject to a constant force F, in the x direction, find its velocity v as a function of t, and by integrating v find its trajectory. Check that in the non-relativistic limit the trajectory is the expected parabola. Hint: The relationship F = P is still true in relativistic mechanics, but now p = ymv instead of p = mv. To find the non-relativistic limit, treat c as a very large quantity and use the Taylor approximation (1+ x)" = 1 + nx when a is small.
