Students in a technology class are racing cars propelled by carbon dioxide cartridges. A burst of gas is released when the seal of the cartridge is broken, and this propels the car down the track. The cartridges are designed to provide a certain impulse. Use the concepts of impulse and momentum to explain why such a cartridge will propel a lighter car to a higher speed.
