(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A load of 200kg rests on a horizontal plane.A horizontal force of 196N is needed to overcome friction.Find the coefficient of friction

2. Relevant equations

F(gravity)=W=mg

F(friction)= (mu)N

3. The attempt at a solution

W=mg

W=200(9.8)=1960N

This then is the F(normal) also.

Now

F(fric)=(mu)N

196=(mu)1960

mu=196/1960=0.2=answer

thanks in advance
