A 100 kg man is three-fourth of the way up a 12 m long ladder (mass=5kg) that is resting aganist a smooth, frictionless wall as shown in the picture. What is the magnitude of the force of friction of the ground acting on the foot of the ladder?
A) Draw all the forces acting on the ladder on the picture, providing a different label for each force (ex: F1, F2)
B) Label the pivot point in your diagram using a big dot, and then determine if the torque due to EACH force that you labled in your diagram (ex: Torque1, Torque2)
C) What are the three conditions for static equilibirum?
D) Use the conditions for static equilibrium to solve for the unknown.

(1) A 4m ladder has mass m= 10 kg. We assume that its centre of mass is half-way along its length. The ladder is leaning against a wall at an angle of 30° from the vertical, as shown in the figure. Suppose that the wall is frictionless smooth and slippery), and that the coefficient of static friction between the feet of the ladder and the floor is H. =0.6. Take the acceleration due to gravity to be g=10m/s" directed vertically...
