The coefficient of friction is 0,25 between both surfaces of the thin, light plate shown in the figure below. Determine the tension in the wire holding the 15 kN block to the wall and then calculate the magnitude of the smallest force P required to start movement of the plate.
![The coefficients of friction μs = 0.40 and μk = 0.30 between all surfaces of contact. Determine the smallest force p required to start the 30 kg block moving if cable AB is attached as shown, [20 marks] A body of weight 2000 N moves on a level horizontal rough road for a distance of 200 m. The resistance of the road is 10 N per 1000 N weight of the body. Find the work done by the resistance on the body. [05 marks]](https://www.doubtrix.com/uploads/editor/0315425849mrfrZNtHac.jpg)
