Blocks A and B, with masses mA = 400 kg and mB = 90 kg, respectively, are initially at rest when block A starts sliding down the incline with θ = 30°.

If friction between the two blocks and between block A and the incline is negligible, use the impulse-momentum principle to determine the velocities of A and B 1.5 s after release.
