1. The problem statement, all variables and given/known data I need to calculate the time that it takes for a drag car that is powered by an 8 gram CO₂ cartridge to go across a certain distance. My wooden drag car is 100 grams. It will be traveling a distance of 50 feet. 2. Relevant equations Force= mass x acceleration Power= work / time Work= force x distance Time= distance / speed Power= force x velocity 1 gram = 0.001 kilograms 1 ft = 0.33 meters 3. The attempt at a solution I've tried to find out how much power is produced by the CO2 cartridge. I could not find an answer, which made me think that maybe I dont need to find power. Also, power is measured in watts and no where in my statement do I mention watts. I do not know the speed of my car yet. How do I calculate the time?
