Unformatted text preview: P axis.) (e) A 150N brick is fastened to the top of the block and the experiment is repeated. Draw the graph of f vs P for this case. Label axes with numerical values as in (d). 2. A wedge with mass M rests on a horizontal tabletop. A block with mass m is placed on the wedge and a constant horizontal force F is applied to the wedge. Both the wedgetabletop surface and the wedgeblock surfaces are frictionless. (a) Draw FBDs for the block, for the wedge, and for the system block+wedge. F m α M (b) What must the magnitude of F be if the block is to remain at a constant height above the tabletop? Express your answer in terms of M, m, α , and g. (c) Optional challenge: Describe how your answer to (b) would change if there were friction at the wedgetabletop surface, at the wedgeblock surface, or both. In each case, is there a unique value of F for the block to remain at constant height?...
