@infobeautiful That's more fun than I'm having today!
Something similar with a cannonball was used to measure the strength of black powder.
This is how you start to think about having a lil space program.
Strikethrough fireworks and call it explosives…
@infobeautiful Fantastic!
For the last charge, the time of flight was 7.48". Assuming no (or negligible) drag, the time to apogee was 3.79". With gravity at 9.80665ms^-2, this gives the initial velocity as 37.17ms-1. For the height of the apogee: h = v0.t - (9.80665 x 3.79 x 3.79)/2 = 70.43m.
Thanks for sharing!
