Best ResponseYou've already chosen the best response.0oh, thanks but i meant how did you solve for that, and how did you get 0.32?

Best ResponseYou've already chosen the best response.1The coefficient of static friction is the ratio of the maximum friction force and the normal reaction between two objects when neither of the objects is moving. (ref. wiki plus corrections)
