Find the normal force exerted by the bottom ladder


A 10.0-kg monkey climbs a uniform ladder with weight w = 1.20 x 10^2 N and length L = 3.00 m. The ladder resrs against the wall at an angle of theta = 60.0 degrees. The upper and lower ends of the ladder rest on frictionless surfaces, with the lower end fastened to the wall by a horizontal rope that is frayed and that can support a maximum tension of only 80.0 N. (a) Draw a freebody diagram for the ladder. (b) Find the normal force exerted by the bottom ladder. (c) Find the tension in the rope when the monkey is two-thirds of the way up the ladder. (d) Find the macimum distance d that the monkey can climb up the ladder before the rope breaks. (e) If the horizontal surface were rough and the rope were removed, how would your analysis of the problem be changed and what other information would you need to answer parts (c) and (d)?
