Homework Help: Physics

Posted by CC on Tuesday, March 31, 2009 at 5:07pm.

The co-efficient for static friction for a 5 kg box on a floor is .72. How much force if required to start the box sliding?
I worked it as follows:
Force of friction=Force normal * co-effic. of friction which is .72*5*9.8=35.28 but answer in back of my book says this is wrong. Where did I err?
