Two blocks are positioned on surfaces, each inclined at the same angle of 41.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 6.20 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.600. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the RIGHT at a constant velocity?     6.20 kg     3.70 kg     32.33 kg     1.19 kg

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
