This week we will investigate conic shapes in the real world.
Begin by selecting Start a New Conversation. Research ONE example of a conic section in real life that has not already been used by a classmate.
Make your choice (Bouncing ball) the subject of your post, and then tell us in your own words about your find. Do not just make this up off the top of your head. The St Louis Arch, for example, is NOT a parabola—it is an inverted catenary.
To get credit for this Discussion, you must cite a source confirming that your example is, indeed, a conic and not some other more exotic curve.
Using a personal example (My eyebrow) will not count unless you can cite a source verifying that eyebrows are parabolic.
