Re: Nerf ball starting at 12m/s 45 degree angle ending at 8ft 6in w/ air resistance

someone has suggested the first step in another thread: drop one of the balls from a height and measure its terminal velocity (the speed at which its air resistance matches the pull of gravity).

Without real data parameters any calculations will be useless.
We already have something to base the air friction on, FIRST told us that it will travel 35feet at 30 degrees. That is WITH air resistance. We should be able to base our calculations off that.

The 35ft at 30 degrees is with no spin, so we can do some tests with spin afterwards, but lets get the basics first, i.e. without spin.
