A uniform ladder weighing 100 N leans against a smooth vertical wall such that it makes a slope of 1:4. A human stands 2 meters up the ladder and has a mass of 70 kg. If the ladder is 5 m long, Find:
A. The force exerted by the wall on the ladder.
B. The magnitude and direction of the resultant force exerted by the floor on the lower end of the ladde
A)
"F_1=600~N."
B)
"F_2=350~N."
