Answer:
Explanation:
Let the normal force of the wall on the ladder be N2 and the normal force of the ground on the ladder be N1.
Horizontal forces:
[1]
Vertical forces:
[2]
Substitute [2] into [1]:
![N_2 = (u1)*[m*g - (u2)(N_2)]](https://tex.z-dn.net/?f=N_2%20%3D%20%28u1%29%2A%5Bm%2Ag%20-%20%28u2%29%28N_2%29%5D)
![N_2= \frac{(u1)m*g}{[1 + (u1)(u2)]}](https://tex.z-dn.net/?f=N_2%3D%20%5Cfrac%7B%28u1%29m%2Ag%7D%7B%5B1%20%2B%20%28u1%29%28u2%29%5D%7D)
[3]
Torques about the point where the ladder meets the ground:
![[1 + (u1)(u2) - 2(u2)(u1)]/2 [1 + (u1)(u2)]= [(u1)/[1 + (u1)(u2)]]cot\alpha](https://tex.z-dn.net/?f=%5B1%20%2B%20%28u1%29%28u2%29%20-%202%28u2%29%28u1%29%5D%2F2%20%5B1%20%2B%20%28u1%29%28u2%29%5D%3D%20%5B%28u1%29%2F%5B1%20%2B%20%28u1%29%28u2%29%5D%5Dcot%5Calpha)
tanα = 
Independent, and inverse means if one variable increases then the other decreases, direct is when they both go up or down together.
