Study the diagram shown below. Assume the box is accelerating to the right at 1.1 m/s/s. m = 5.0 kg F = 12 N What is the coefficient of friction between the object and the surface?yes Normal force is here N = mg N = ( 5 . 0 k g ) x ( 9 - 8 1 m S N = 49. 05 Newton. so, Value of Norway force is 49 .05N
