In the figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.3 kg, block B has a mass of 2.2 kg, and angle 9 is 32°. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 28 cm? Number i Units B
