The 454-N force is applied to the 80-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 = 0.73 H = 0.56 39° P = 454 N
