The 440-N force is applied to the 91-kg block, which is stationary before the force is applied. Determine the magnitude and direction of the friction force F exerted by the horizontal surface on the block. The force is positive if to the right, negative if to the left. H₂ = 0.64 M = 0.41 Answer: F= i 30° N P = 440 N
