Hey Y'all;
A design being checked out in Open Rocket ( am new user of program) shows in flight simulation result tables a "Ground hit velocity" of 12 point something feet per second for a 5 oz rocket with an 18 inch diameter plastic parachute.
That gives rise to a question about descent - what is a practical range for ground hit velocity?
I look at my height and think something falling 6ft per second is going to land with a thump, let alone twice that per second.
