The path of the airplane and the guideline lie in the same horizontal plane because the weight of the plane is balanced by the lift generated by its wings. Find the tension in the 17 m guideline for a speed of 19 m/s. Tension is the centripe ...

... A student sits on a rotating stool holding two 3.0-kg objects. When his arms are extended horizontally, the objects are 1.0 m from the axis of rotation and he rotates with an angular speed of 0.75 rad/s. The moment of inertia of the student plus stool is 3.0 kg ∙ m2 and is assumed to be constant. Th ...

Circular Motion Chapter
... Often more than one force is acting on an object...including an object traveling in uniform circular motion. In that case, you treat this case the same way you did in any dynamics problem, the sum of the forces matters...not any one force. So for instance, if we changed the prior example by having t ...
