Question

1. Wet clothes tend to stick to the inside of the washing macgines after they are spun in the drum. Can you explain why using what you learn in the lab?

2. you are swinging on a tire swing with a fraying rope. At what point while you are swinging is the rope most likely to break? explain

3. consider a rock at the bottom oa a bucket that is being swung in a full vertical circle. If the bucket is rotated quickly enough, the rock willl be held in place even when the bucket is upsidde down. How is this possible since the only forces acting on the rock are the normal forces from the bucket and gravity-an both of these forces are directed downward?

Explanation / Answer

Q1.

as an object is spun, due to centripetal force which is radially outward directed, the wet clothes stick to the inside of the washing machine

Q2.

when you are swinging, tension in the rope=centripetal force+component of weight along the direction of the rope

component is highest when the rope is vertical.

so tension in the rope is highest when the rope is vertical.

and that is the most likey point when the rope will fray.

Q3.

the centripetal force on the rock which is due to the circular motion acting radially outward holds the rock sticking to the bucket if it is high enough to overcome the downward pull of gravity.
