1. The problem statement, all variables and given/known data An object rests on an inclined plane. One end of the plane is lifted until the object begins to slide. The angle at which the object begins to slide is 35 degrees. What is the Coefficient of Friction 2. Relevant equations fk = µkFn fsmax=µsFn 3. The attempt at a solution Honestly, I don't even know where to begin on this one. Only one variable is given, in what looks (to me) to be a problem where more than one variable is called for to be solved. Similarly.... 1. The problem statement, all variables and given/known data Nike uses a sole for a line of shoes that has a coefficient of friction, µ=.3. Find the maximum acceleration that a runner using these shoes can have.
