62. The notation and coordinates are as shown in Fig. 12-6 in the textbook. Here, the ladder's center of mass is halfway up the ladder (unlike in the textbook figure). Also, we label the x and y forces at the ground f s and F N , respectively. Now, balancing forces, we have Σ F x = 0 ¡ f s = F w Σ F y = 0 ¡ F N = mg Since f s = f s , max , we divide the equations to obtain
