A light elastic string, of natural length 1m and modulus of elasticity 21.6 N has one end attached to a fixed point O. A particle of mass 2 kg is attached to the other end. The particle is held at a point which is 3 m vertically below O 4. and released from rest. Find (a) the speed of the particle when the string first becomes slack, i.e. when there is no tension in the string: (b) the distance from O when the particle first comes to rest.
