9. A 10kg wooden block rests on a 5kg, L-shaped piece of metal as shown below. The metal, in turn, rests on a frictionless surface. The coefficients of friction between the wood and the metal are us = 0.40 and pk = 0.30. (a) What is the maximum force that can be applied if the 10kg block is NOT to slide %3D relative to the metal? (b) What is the corresponding acceleration of the piece of metal? F Pulley Block Frictionless Surface
