1. A 4 kg block is placed on a smooth 30° incline and released from rest, but a string connected to the block runs up the incline parallel to the surface, over a frictionless pulley, and horizontally to a 6 kg block on a level surface with a kinetic friction coefficient of 1/6. Find the acceleration of the system and the speed at the end of 4 s assuming the 6 kg block doesn't run into the pulley first.
2. A light rope is tied to the ceiling and then strung through a pulley mounted on a block that is subsequently lifted straight up at a constant acceleration of 0.2 m/s² by pulling upward on the free end of the rope. Find the tension in the rope and the acceleration of its free end if the mass of the block and pulley combined is 6 kg.
Please show how its done, thank you!

A box (mass 25.8 kg) sits on a rough incline that makes an angle α = 28.1o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.455 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for which this...
