How does mass affect the launch of a catapult and the projectile flight?? 1. The problem statement, all variables and given/known data How does the mass of the projectile affect the projectile as it is being lauched and after it is launched? Could your catapult launch a tennis ball and a boulder equally well? Once in flight, explain what the effect of the mass of the projectile is. 2. Relevant equations N/A 3. The attempt at a solution I know that the mass does not change the flight of the projectile. Right? I do not know what to put for it being launched though.. If I put : Mass does not affect anything, would that be right?
