The drawing shows a circus clown who weighs 750 N. The coefficient of static friction between the clown’s feet and the ground is 0.630. 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?

Answer 1

Your posting speed is impressive, at less than 20 second interval for 7 posts.

However, your efforts in solving problems is at the other extreme.

The more effort you show, the more chance that help will be given in priority. In fact, you are encouraged to post a problem, study the help/response, and try to solve some by yourself before posting the others.

What you just did qualifies for homework/test dumping.
