This program results in two graph outputs. 1.Drag force vs Velocity ( Co-efficient is constant, velocity varies) 2.Drag Force vs Drag Coefficient (Velocity is constant, Drag Coefficient varies) The Drag force vs Velocity Graph shows that for increasing velocity the force increases exponentially since velocity^2 is…
