Since the floor is rough, it exerts both a normal forceN1 and a frictional forcef1 on the ladder. However, since the wall isfrictionless, it exerts only a normal force N2on the ladder. The ladder has a length of L = 4.1 m, aweight of WL = 58.5 N, and restsagainst the wall a distance d = 3.75 m above the floor. Ifa person with a mass of m = 90 kg is standing on theladder, determine the following.
(a) the forces exerted on the ladder when the person is halfwayup the ladder (Enter the magnitude only.)
N1=
N2=
F1=
(b) the forces exerted on the ladder when the person isthree-fourths of the way up the ladder (Enter the magnitudeonly.)
N1=
N2=
F1=
