70psi 1.5 diameter barrel potato mass=.25kg barrel length= 3.2m does somone want to do this math for me cause my brain just aint working right now and i dont have time. let me know if you need anymore info

sorry about the vague question but i built a 9' tall potato cannon and i have no safe place to shoot it thats near by so i cant time how long the potato is in the air for so kinematics is out. i needed to find the buzzel velocity of the cannon without firing it. to do that i need the force the pneum...

how can you find the force in Newtons without using kinematics and only using the size of your air tank and what psi its at?
