WebIt's not equal to "m" "g" "sin(theta)" it's equal to the force of kinetic friction "mu" "k" times "Fn" and the "mu" "k" is going to be 0.2, you have to be careful because the "Fn" is not just equal to "m" "g" the reason is that on an incline the normal force points this way so the normal force doesn't have to counteract all of gravity on an ... Web16 dec. 2014 · But the value of ## \mu_{s}= \mu_{k}=0.5## so numerically Frictional force is always equal to 0.5N. Reply. Nov 16, 2014 #118 ... The static friction is a limit, not a defined value. Fs≤μ s N while the kinetic friction is Fk=μ k N.When the ball rolled we used the condition that the angular velocity of rotation was the same as the angular ...
