# How do you find the differential equation of motion?

A rope of mass M and length L lies on a frictionless table, with a short portion Lo hanging through a hole. Initially the rope is at rest.

1) Find a general equation for x(t), the length of rope through the hole.

2) Evaluate the constants A and B so that the initial conditions are satisfied
