Block A, with a mass of 10 kg, rests on a 30% incline ,The coefficient of kinetic friction is 0.20. The attached string is parallel to the incline and passes over a massless, frictionless pulley at the top. Block B, with a mass of 3.0 kg, is attached to the dangling end of the string . Find the acceleration of B (magnitude and direction);
