50 kg block of weight W, acted upon by a force P = 100N at an angle a = 30°, as shown, is resting on a horizontal surface. The coefficients of friction between the block and the surface are μs, = 0.30 and μk = 0.25. The force exerted by the surface on the block is 440.5 N. a. What is P in component form? b. At the instant shown, what is the frictional force, f, between the block and the surface? c. What is the magnitude of the angle of friction? d. What is the resultant, Rfn, of the frictional force f and the normal force N?
