Block Awith a mass of 10kg, rests on 30 degree incline.The coefficient of kinetic friction is 0.20. The attached string is parallel to the incline and passes over masskess frictionless pulley on top. Block B with mass of 3.0kg is attached to the dangling end of the string.
Express the weight of Block A as a som of x and y components with the possitive x axis going up the slope. Use unit vector notation
