Homework Help Forum: last one! science!

Posted by please help(: on Wednesday, October 28, 2009 at 3:49pm.

A typical high school lab activity involves building a model rocket with a small canister, antacid, and water. The water and antacid are combined in the canister, which is then tightly closed and turned upside down. The reaction of these materials in the canister causes gas to form, leading to a pressure buildup in the canister. This pressure causes the canister to eventually burst open and fly into the air. What can be done to increase the momentum of this miniature rocket as it is flying into the air? Hint-The formula for momentum is p = mv Please help this is my LAST question!

  The force on the cannister is equal to pressure*area top. So the pressure before exploding has to increase. So the cap has to be on tighter. Figure out how to do that....
