I've calculated the drag constant for a tennis ball (v^2 * -6.15x10^-4) and we know that vf=vi+at and df=1/2at^2+vit+di. But how would I be able to calculate the velocity and displacement at any given time, if I encompassed air resistance?
To anyone who wants to know, you can find the force of drag at any given time by: (vi+at)^2 or (-9.8t+vi)^2, where down is negative, and multiply that by the drag constant. So if you through a ball UP in the air at 30 m/s, the drag at any given time would be: f(x)=(-6.15x10^-4)*(-9.8t+30). So I want to know how to put this together in one function to find the displacement or velocity at any given point, including air resistance. Thanks!
