Homework Statement



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

Homework Equations


F(gravity)=W=mg
F(friction)= (mu)N


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

Looks good.
 
looks good... except for the part 196/1960 = ... well not .2 XD
 
Oops >.<
 
Thanks for all the help.Yes, it was a typo...i know it should be 0.1 :)
