The screenshots of the graphs are attached. The first graph is a velocity graph of a basketball with respect to time, and it is assumed that it has been launched at an angle of 45 degrees and an initial velocity of 10 m/s. Due to air resistance, which I was able to include using Euler method, spreadsheet, and LoggerPro, the velocity asymptotically approaches -20m/s, which actually is the terminal velocity of a falling basketball.
However, I don't know what kind of equation is behind that graph.
The second graph is the deceleration from the air resistance, and I don't know what the equation for that one is either.
Fd = 0.5 * Cd * rho * A * v^2
The Attempt at a Solution
I can't even guess what those graphs consist of...
