Two blocks are positioned on surfaces, each inclined at the sameangle of 52.5 degrees with respect to the horizontal. The blocksare connected by a rope which rests on a frictionless pulley at thetop of the inclines as shown, so the blocks can slide together. Themass of the black block is 5.05 kg, and the coefficient of kineticfriction for both blocks and inclines is 0.510. Assume staticfriction has been overcome and that everything can slide. What ismust be the mass of the white block if both blocks are to slide tothe LEFT at a constant velocity?
