606-607/6086. Two particles,respectively, and are attached to the ends of alight in extensible string. The string passes over a small smooth pulley fixed above a horizontal floor, as shown. Both particles are held with a taut string at a height of 1m above the floor. The particles are released from rest and in the subsequent motion B does not reach the pulley.

a) Find the tension in the string immediately after the particles are released. b) Find the acceleration of A immediately after the particles are released.When the particles have been moving for 0.5 s, the string breaks. c) Find the further time that elapses before B hits the floor.
