- Q1 : a function (that takes in velocity and the initial angle) that plots the trajectory of the ball with no drag, as the forwardEuler and analytical solutions
- forwardEuler : the forward euler metherd
- trajectory_eq : this is the analytical soluton for the trajectory
- dxdt : ODE
- dydt : ODE
- trajctory_drag : the script that plots the trajctory for drag
- dxdt_drag : ODE
- dydt_drag : ODE
#TODO
- Q4 : the script that plots the trajctory for drag and the magnus effect
- forwardEuler_mag : forward with omega as an input
- dxdt_mag : ODE
- dydt_mag : ODE
