1. The problem statement, all variables and given/known data Blocks 1 and 2 of masses m1 and m2, respectively, are connected by a light string. These blocks are further connected to a block of mass M by another light string that passes over a pulley of negligible mass and friction. Blocks 1 and 2 move with a constant velocity v down the inclined plane, which makes an angle [tex]\theta[/tex] with the horizontal. The kinetic frictional force on block 1 is f and that on block 2 is 2f. determine the coefficient of kinetic friction between the inclined plane and block 1. and Determine the value of the suspend mass M that allows the two blocks to move with constant velocity down the plane 2. Relevant equations (sum of forces) = (mass)(acceleration) (kinetic friction force)=(kinetic friction coefficient)(normal force) 3. The attempt at a solution I set the sum of the forces equal to zero for both the vertical and the horizontal components, but I don't think they came out right.
