need help po, thank you!

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. H = 0.73 Hk = 0.56 Answer: F = i -363.76 39° N P = 454 N
