I have attached a diagram of what I am trying to do. This is a side view of a tube that will be carrying that ball up through the curve and back in the opposite direction, just 50 cm higher. The ball is hard plastic and the curved tube is probably going to be hard plastic as well but sprayed w/ teflon. Basically, I need to figure out how much force or energy is required to launch that ball through the tube and out the top.(adsbygoogle = window.adsbygoogle || []).push({});

I am confused about which formulas apply and which don't. I would appriciate help deriving the formulas so I can tweak the numbers to make this design work best for my project.

Thanks for the help
