3. A 3m long uniform ladder of mass m = 10 kg leans up against a frictionless wall as shown. The ladder resting on the floor experiences a coefficient of friction, µs = 0.4. The angle the ladder makes with the horizontal is 0. А. What is the minimum angle, 0, (non-zero!) the ladder can make with the horizontal and not slip? В. If you now place the ladder at an angle 0 = 60°, what is the magnitude and direction of the frictional force on the ladder? С. 70kg man get without the ladder slipping? With the ladder at that same 60° angle, how high off the ground could a
