a 100kg man is standing three fourth of the way up a 12m long ladder (mass 5kg)that is resting against 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
b) label the pivot point in your diagram above (using a big dot) and then determine the torque due to each force that you labeled inyour diagram (ex f1...f2..etc) Pay attention to the signs!
c) what are the 3 conditions for static equilibrium?
d) use the conditions for static equilibrum 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...
