 comment Recognizing a measure whose moments are the motzkin numbers
A side remark: this non-centered semicircle distribution whose moments are the Motzkin numbers appears in some problems connected to quantum information theory, see e.g. arxiv.org/abs/1011.0275. If this showed up in another context, I'm very interested !

 comment Convex bodies with symmetric shadows.
For the first question, yes. This is a theorem due to Blaschke and Hessenberg, see Theorem 2 in C.A. Rogers, "Sections and projections of convex bodies", purl.pt/2464/1/j-5293-b-vol24-fasc2-art3_PDF/…
