Best ResponseYou've already chosen the best response.0@ swin u need to know what plane u are working on is it an incline plane or an horizontal plane/

Best ResponseYou've already chosen the best response.0coefficient of static friction=static frictional force/ normal rection

Best ResponseYou've already chosen the best response.0I assume the plane is horizontal: the normal reaction=weight=mg ur

Best ResponseYou've already chosen the best response.0@hubertH it doesn't say. so i assumed it was horrizontal

Best ResponseYou've already chosen the best response.0so u knw how to get to the answer right?

Best ResponseYou've already chosen the best response.0but is static friction only involved in inclined plane?

anonymous

Best ResponseYou've already chosen the best response.0No.. then I wouldn't be asking lol

Best ResponseYou've already chosen the best response.0No! static friction is the force required to set the body in motion in our case it 's given as 258.0N

Best ResponseYou've already chosen the best response.0Well they're asking from the coefficient of static friction?

Best ResponseYou've already chosen the best response.0so i say that Fnet = \[\mu _{s}  Fg = ma?\] a little do you?

Best ResponseYou've already chosen the best response.0well if it's starting to move wouldn't it be Ff = Mu(s) Fn?

anonymous

Best ResponseYou've already chosen the best response.0\[mus =\frac{ ?Fmus }{Nr ? }\]

anonymous

Best ResponseYou've already chosen the best response.0Nr is ur normal reaction=mg

Best ResponseYou've already chosen the best response.0Ok so it's just normal force (Fn)

Best ResponseYou've already chosen the best response.0and since it's horizontal Fnet = 0N

anonymous

Best ResponseYou've already chosen the best response.0what is Fnet standing fo?

anonymous

Best ResponseYou've already chosen the best response.0If they ask for acceleration and give kinetic friction is it still the same equation except it's Mu(k)  Fn = ma?

anonymous

Best ResponseYou've already chosen the best response.0no! kinetic friction is the smallest force that keeps the system moving @ constant speed
