Rearranging the equation, we have μs = Fc / N = fs/mg. Substituting the values given, we can calculate the value of μs.Also, the static friction would never be larger than the weight component - because then there would be a net force up along the incline, and the ball would start rolling upwards. This also doesn't actually happen, so that also can't be true. The true situation must be that the static friction is smaller than the weight component.a) Calculate the force that Elton has to apply to keep the piano from accelerating.

If the coefficient of static friction is large enough, the top block will be dragged along to the right by the force of friction from the bottom block. If the coefficient of static friction is not large enough, the top block will "slide off" the bottom block. In the second case, kinetic friction would take over. μs = 0.25. N = 20 N.
