An 8kg block sits on a steep incline at a 50degree angle. It is prevented from sliding by some applied force F parallel to the surface as shown. If the coefficients of kinetic and static friction between the incline and block are .45 and .55 respectively, then what is the smallest force Fmin needed to prevent the block from sliding?
