MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 14.0 m uniform ladder weighing 490 N rests against a frictionless wall. The ladder makes a 55.0 angle with the horizontal (a) Find the horizontal and vertical forces (in N) the ground exerts on the base of the ladder when an 020-N firefighter has climbed 3.90 m along the ladder from the bottom horizontal force magnitude 33173 ✓N direction towards the wall vertical force 1310 N up magnitude direction (b) If the ladder in just on the verge of doping when the Profighter is 9.20 m from the bottom, what le the coefficiant et static friction between ladder and ground? X It may be helpful to think hrst about the force the wall exerts on the ladder. How is this related to the force that the ground events on the ladder () What 17 tollis spilled on the ground, causing the cofficient of static friction to drop to half the value found in part (b), what is the maximum distance in frighter can climb along the Indder from the bottom before the ladders 0.43 Need Help?
A 11.8-kg monkey climbs a uniform ladder with weight w = 1.10 x 102 N and length 2 = 3.35 m as shown in the figure below. The ladder rests against the wall and makes an angle of 0 = 60.0° with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope that is frayed and can support a maximum tension of only 80.0 N Rope (a) Draw a force diagram for the ladder.
