Measuring the coefficient of friction of a skater on …

WebThe coefficient of kinetic friction between the blades of her ice skates and the surface of the rink is 0.04. If she slides a distance of 14.8 m before stopping and her push against the wall lasted 0.2 s, what was the average force (in N) that she exerted on the wall? Expert Answer 100% (4 ratings) WebThe coefficient of friction is the ratio between the force slowing something down and the force pushing them together. The larger it is the stronger friction is (and the more the object is slowed down). For example, a person's skates on ice have a small coefficient of friction, but rubber on concrete has a big one.
