Physics questions and answers. v Part 1: Determine the Force Exerted by Rocket The video below shows a student, Emilio, riding a cart powered by a fire extinguisher that has been modified to act as a rocket. The fire extinguisher …
Since the gas disperses quickly, this type of fire extinguisher is only effective from 3 to 8 feet. There is not one set pressure for all fire extinguishers, they vary by class. The ones they use in firehouses are 690 kPa but the pressure in carbon dioxide extinguishers can go up to 5861 kPa. Victoria Poon — 2005.
1. Here is the graph that Emilio recorded during this
Science; Physics; Physics questions and answers; Question:
Like the balloon, the fire extinguisher pushes air out in one direction, so the fire extinguisher, the cart, and the rider go in the other direction. Warnings: Straighten out the balloon so it will go away from you in a straight line, and not make a confusing loop. The handle on the fire extinguisher is really easy to press down.

How does a Halon fire extinguisher work?
A halon fire extinguisher contains a gas that interrupts the chemical reaction that takes place when fuels burn. A water fire extinguisher contains water and compressed gas and should only be used on Class A fires. A carbon dioxide fire extinguisher will be most effective on Class B and C fires.
What are the different types of fire extinguishers?
Each one can extinguish different types of fire: wood, cloth, paper, rubber, plastics flammable liquids such as gasoline or oil electrical equipment such as fuse boxes or circuit breakers combustible metal such as magnesium used in kitchens and environments where the probability of a grease fire is higher, this class was introduced in 1998.
