1. The problem statement, all variables and given/known data I'm trying to find the acceleration due to air resistance in x direction and acceleration due to air resistance +gravity in y component. given variables m-0.14273(baseball) Cd=0.4 Vi=20m/s angle= 45 degrees Basically, I have to program a projectile motion program accounting air resistance, but my biggest problem physics wise is my huge ax, and y acceleration, which prevent my program to loop even more:/ 2. Relevant equations ax= fairx/mass = -cdVix^2/mass ay= fairy+fg 3. The attempt at a solution fairx= (0.4)(20cos45)^2=80N ax= 80n/0.14263kg = 560.498844m/s^2 ay = well....its in the thousands >.> does this mean i have to assume f=Cd*V instead of being proportional to V^2?
