Q9.29Multiple choice
A stone of mass m is tied to an elastic string of negligble 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.
- (a)Find the distance y from the top when the mass comes to rest for an instant, for the first time.
- (b)What is the maximum velocity attained by the stone in this drop?
- (c)What shall be the nature of the motion after the stone has reached its lowest point?
