The drawing shows a circus clown who weighs 890 N. The coefficient of static friction between the clown’s feet and the ground is 0.590. He pulls vertically downward on a rope that passes around three pulleys and is tied around his feet. What is the minimum pulling force that the clown must exert to yank his feet out from under himself?

You are trying to determine the coefficient of static friction between your shoe and the floor. To do so, you place your shoe on the ground, attach a spring scale, then pull horizontally on the shoe until it just barely starts to move. You take note of the spring scale reading at that moment. Then you put some known extra masses into your shoe and repeat the process several times. (a) What is the purpose of adding extra masses and...
