A block of mass 25 kg is held at rest on a rough plane inclined at an angle of 15 super ring operator to the horizontal, by a rope making an angle of 65 super ring operator to the plane. The block is on the point of slipping up the plane. The coefficient of static friction between the block and the plane is 0.14 . Calculate the magnitude of the friction force, in newtons, to two significant figures. (Take the magnitude of the acceleration due to gravity, g , to be 9.8 m s super negative two .)
