7. Friction, Inclines, Systems

Inclined Planes

Vectors on an inclined plane, and how normal force compares to weight. Vector components on incline.

Runaway Ramp

<p>A 4.0-kg box sits on a frictionless inclined plane that makes a 21° angle with the horizontal. It is held in place by a cord parallel to the plane. Calculate the tension in the cord.</p>
