8. A uniform ladder of mass 12 kg and length 8 m is leant against a smooth wall. The base of the ladder is 4.5 m away from the base of the wall. You may assume the flat surface is rough. (a) Draw a sketch of the system indicating all the forces acting on the ladder. (b) Calculate the angle the ladder makes with the flat surface and the height the ladder reaches up the wall. (c) Calculate the magnitude and direction of the contact force that the ladder makes with flat surface.
