College Physics 8th Edition, Serway and Vuille Problem number 88- Chapter 8 A 10.0-kg monkey climbs a uniformladder with weight w= 1.26x102 N and lengthL = 3.10 m as shown inthe figurebelow. The ladder rests against the wall at an angleofθ = 53°. The upper and lower ends of the ladderrest onfrictionless surfaces, with the lower end fastened to thewall by ahorizontal rope that is frayed and that can support amaximumtension of only 80.0 N. (a) Draw a free-body diagram for the ladder. (Do this onpaper.Your instructor may ask you to turn in this work.)
(b) Find the normal force exerted by the bottom of theladder.
________ N
(c) Find the tension in the rope when the monkey is two-thirdsofthe way up the ladder.
_________N
(d) Find the maximum distance d that the monkey canclimbup the ladder before the rope breaks. _________m
(e) If the horizontal surface were rough and the rope wereremoved,how would your analysis of the problem be changed and whatotherinformation would you need to answer parts (c) and (d)?
