Two blocks, each of mass M are connected by a string of length l. One
block is placed on a frictionless table and the other is hung over the
side of the table by means of a frictionless, massless pulley. Assume
that at time t=0 the second block?s height is even with the table and
motionless.
a)	Write the Lagrangian of the system for the case of the string being
massless and when the string has mass m.
b)	Write the equations of motion for this system in both cases.
c)	Write the Hamiltonian for this system, with the massless string.
