Practice Quiz 8 Physics 7B Winter 2010 Mar. 03, 2010 A 2 m tall 80 kg man is leaning against a smooth (frictionless) wall. The axis from his shoulder to his shoes makes a 60 degree angle with respect to the horizontal. This axis is 170cm. The man’s center of gravity is 100 cm from his feet. Assume that there is a frictional force between the floor and the man’s shoes. a) Indicate the magnitude and direction of the various forces
