In a three pulley system a man who weighs 875.0N is standing upright holding on one end of the rope while the other end is tied to his feet. The coefficient of static friction between the man's feet and the ground is 0.41. He pulls vertically downward on a rope that passses around three pulleys and is tied around his feet. The pulleys and rope are assumed to be massles and frictionless.

A.) List five forces acting ono the clown and specify their directions.

B.) What is the minimum pulling force that the clown must exert to yank his feet out from under himself?

C.) Estimate the normal force from the ground.

D.) Estimate the static friction from the ground just before he starts moving.
