9. A 2.05-kg block is pushed against a wall with a force of magnitude P such that the block slides vertically down the wall at a constant speed. The force P is directed perpendicular to the wall and the coefficient of kinetic friction between the wood and the wall is p, = 0.265. 8 N k %3D (a) What is the direction of the friction force on the block by the wall? 1. Downward 2. Upward 3. Out of the wall 4. Into the wall ΣΕ T or (b) Determine the magnitude P of the pushing force. 75
