3. If you wanted the athletic shoe to slide faster on a surface, what might you do to the shoe? Provide at least two ways to make the shoe slide faster, and explain in terms of the force of friction and the coefficient of friction.

In order to make the athletic shoe to slide faster of a given surface you had to reduce the friction coefficient of the shoe with the surface.

One way to do that is to put some grease of the sole of the shoe, which undoubtedly would reduce the friction coefficient drastically and the shoe would slide more easily.

Also, if you make the sole smoother the shoe the friction coefficient would decrease and, again, the show would slide mor easily.
