Conservation of Energy

In the figure which is shown at “click here” , the pulley has negligible mass, and both it and the inclined plane are frictionless . Block A has a mass of 1.0 kg , block B has a mass of 2.0 kg , and angle theta is 30 degrees . If the blocks are released from rest with the connecting cord taut , what is their total kinetic energy when block B has fallen 25 cm ?
