A stone of mass m is tied to an elastic string of negligible mass and spring constant k. The unstretched length of the string is L and has negligible mass. The other end of the string is fixed to a nail at a point P. Initially the stone is at the same level as the point P. The stone is dropped vertically from point P. What is the maximum velocity attained by the stone in this drop?

Question

A stone of mass m is tied to an elastic string of negligible mass and spring constant k. The unstretched length of the string is L and has negligible mass. The other end of the string is fixed to a nail at a point P. Initially the stone is at the same level as the point P. The stone is dropped vertically from point P. What is the maximum velocity attained by the stone in this drop?, v=(2gL+2mg 2 /k) 1/2, v=(gL+2mg 2 /k) 1/2, v=(gL+mg 2 /k) 1/2, v=(2gL+mg 2 /k) 1/2
