A worker moves a 20-kg crate on a level surface by pulling on the free end of a light, uniform cable whose other end is attached to the crate.

A block with mass m1 = 8.7 kg is on an incline with an angle θ = 37° with respect to the horizontal. The coefficients of friction are: μk = 0.36 and μs = 0.396. Another block with mass m2 = 15.5 kg is attached to the first block. The new block is made of a different material and has a greater coefficient of static friction. What minimum value for the coefficient of static friction is needed between the new block and the plane to keep the system from accelerating?

The velocities of m1 and m2 are V1 and V2 and it is V1>0 and V2<0 . The accelerations of the masses are a1, a2, a3. Ropes and pulleys are massless and frictionless.
