I'll start the discussion and you handle the analysis. So, without further ado...SOMEONE, PLEASE EXPLAIN THIS:.GIF of a golf ball hitting a Thu, 03 May 2018 16:38:18 GMT https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151659#M59660 ryankelley 2018-05-03T16:38:18Z Re: Golf Ball Physics Challenge https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151660#M59661 <HTML><HEAD></HEAD><BODY><P>Okay, you've got a closed elastic membrane surrounding a viscous fluid; but the math is going to be horrendous.</P></BODY></HTML> Thu, 12 Dec 2013 16:11:10 GMT https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151660#M59661 Fred_Kohlhepp 2013-12-12T16:11:10Z Re: Golf Ball Physics Challenge https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151661#M59662 <HTML><HEAD></HEAD><BODY><P>Is it a fluid?

I'm also unsure of the date of this video capture, so I'm unclear on the actual contents of the golf ball core. I included the above photo to provide some context, but with the recent developments in golf ball components can't say with any clarity what's inside.</P></BODY></HTML> Thu, 12 Dec 2013 16:29:38 GMT https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151663#M59664 ryankelley 2013-12-12T16:29:38Z Re: Golf Ball Physics Challenge https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151664#M59665 <HTML><HEAD></HEAD><BODY><P><IMG __jive_id="63586" class="jive-image-thumbnail jive-image" onclick="" alt="golf.png" src="https://community.ptc.com/legacyfs/online/63586_golf.png" width="450" /></P></BODY></HTML> Thu, 12 Dec 2013 16:52:36 GMT https://www.ptcusercommunity.com/t5/Mathcad/Golf-Ball-Physics-Challenge/m-p/151664#M59665 ValeryOchkov 2013-12-12T16:52:36Z
