In the Figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.7 kg, block B has a mass of 2.7 kg, and angle θ is 27 °. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 20 cm?

Ke = Pe so is it just [mass x gravity x height] = (4.4) (9.8) (0.2) = 8.624 J?
