A block with mass m1 = 8.6 kg is on an incline with an angle θ = 35.0° with respect to the horizontal.
The coefficients of friction are: μk = 0.32 and μs = 0.352.
Now a new block with mass m2 = 16.9 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?
