We are building an air cannon that shoots a wad of paper. I know the volume of the tank, the pressure of the tank, the size of the barrel, and the weight of the object. I need to know how to solve for initial velocity given this information. I will use the Vi to find the estimated distance. Weight 4.5 grams Max Pressure = 150 PSI Tank Volume = 1.25 liters Barrel Diameter = 1 inch Do I need more information? Thank you!
