Depends on the plywood. I can put my Estwing 24 through some pieces of half inch. I don't think my hammer head speed is 140.

This reminds me of a story. One time, I was at a co-workers house, and he gave me some chocolate that he didn't want. He was diabetic and said he got it as a gift, but shouldn't eat it. Anyway, it was kind of like a hard fudge, and I didn't want it, but I took it to be nice. I was riding home shotgun with a friend, and he thought the best thing was to throw it at a road sign. So I did, out the side of his turbo coupe going about 65 mph. Wouldn't you know it, that piece of chocolate went straight through that fiberglass sign!
