A pagej to your private dropbox by 11:59 pm (12/13). 1. Haley the firefighter (800 N) stands on a 10.0-m long ladder (200 N) that leans against a smooth vertical wall. The ladder makes an angle of 50° with respect to the horizontal ground. Haley stands 5.0 m up from the bottom of the ladder (not vertically from the ground). Determine the magnitude and direction of the forces on the ladder by the wall and the ground. Hint: Neglect the...

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...
