A robot pushes a 20-kg giftbox on the horizontal surface as part of the moving job for the holiday season, the force is 79 N to the right as shown. The box does not move. The coefficients of friction between the floor and box are μs = 0.75 and μk = 0.40. What is the magnitude (absolute value) of the friction force on the box, in Newtons? Use g = 10 m/s2.
