Problem
A block of mass m is placed on a rough inclined plane that makes an angle θ with the horizontal. A horizontal force P acts on the block, directed up the slope. If the block is on the point of moving up the plane, derive an expression for the minimum value of P in terms of m, g, θ and the coefficient of static friction μs.
