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 xand yforces at the ground fsand FN, respectively. Now, balancing forces, we haveΣFx= 0¡fs= FwΣFy= 0¡FN= mgSincefs= fs, max, we divide the equations to obtain
