Calculate the …If the coefficient of static friction between them is 0.35 0.35, find the mass of the box. Solution: The box is initially at rest, and a force of 300\, {\rm N} 300N puts it on the verge of motion. So, this external force must be enough to overcome the maximum force of static friction, F=f_ {s, max}=\mu_s F_N F = f s,max = μsF N .where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction.

However, the coefficient must be multiplied by the centripetal force (m X v^2/r), not the weight force (mg). To find the minimum coefficient μs of static friction between the road and the car, we need to equate the centripetal force (Fc) to the maximum static friction force (fs). Rearranging the equation, we have μs = Fc / N = fs/mg. Substituting the values given, we can calculate the value of μs.Chances are, most of us (that have hair aQuestion: Determine the minimum coefficient of static frict This problem has been solved!
