A rope of mass M and length L0 lies on a frictionlesstable with a length 'l' initially hanging ove theedge. How fast is the rope moving when the other end of therope leaves the table? (Hint: the force is a function ofpostion and use x as the variable as you solve for the velocity andconsider the mas per unit length).
