A string with one end fixed on a right well , passing over a fixed frictionless polley at a distance of `2` m from the well , has a point mass `M = 2kg` atteched to the it at a distance of I m from the well . A mass `m= 0.5` kg atteched at the free end is field at rest as this the
string is horizental between the wall and the palley when will be the speed with which the mass `M` with hit the well when the mass `m` is relesed ?
