A is a fixed point at a height H above a perfectly inelastic smooth horizontal plane. A light inextensible string of length L (gtH) has one end attached to A and the other to a heavy particle. The particle is held at the level of A with string just taut and released from rest. Find the height of the particle above the plane when it is next instantaneously at rest.
