4PRACTICE PROBLEM
A wooden block (block W) and a metallic block (block M) are tied together by a lightweight cord and slide down an inclined plane at an angle θ=30∘ to the horizontal. The masses of the blocks are mW=mM=5.0 kg. The coefficients of friction for the wooden and metallic blocks are μW=0.25 and μM=0.35, respectively. Calculate the acceleration of the system as the blocks slide down the incline.
