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 ... 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 ...
WebIn the case of constant kinetic friction, the magnitude of the total energy loss due for an object that slides a distance of d d is simply given by W_\text {fric} = \mu_k N d. W fric = μkN d.
