I really want to buy this model rocket that launches eggs. Egg Rocket Well the rocket can use 4 different kinds of engines. Not all of the engines have the same power, so I know they cant all launch it to the same altitude..the max being about 610 feet. Is there a formula to calculate how high the rocket will go if I have the amount of thrust and the weight of the payload? The weakest engine has 2.7 lbs of thrust and the strongest has 5.6 lbs of thrust. |

sounds like you need the ballistic trajectory equation or you could use the rocket equation my.execpc.com/~culp/rockets/rckt_eqn.html#Method |

This linkwill show you why you dont want a forumla, rather a nice little tool. This link will solve your issue if you can figureout which motor u are using. In addition your motor produces that force for how long? Time is a big factor in that formula you are looking for. unless by lbs of thrust you mean newton seconds Also dont kill your self. I just bought the one the guy at the store pointed me too;) This may also help. NAR |
Lol my point exactly. Not an easy calc for most avg joes. My self included.

I could do it, I just dont want to.. Tired that and I get paid to do rocket science these days
