The drawing shows a circus clown who weighs 850 N. The coefficient of static friction between the clown's feet and the ground is 0.40. 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?

Last night while out on the deck at about 11:30, I observed a very bright patch in the sky, as I looked directly at it, it would slowly moved apart and disperse, but i could see it peripherally! Both my husband and myself observed it for quite some time, does anyone know what this may be? We are in Northern Pennsylvania if that helps?
