4. A 1-kg cannon ball is launched with an initial velocity of 40 m/s into a 20-m/s headwind. The aerodynamic drag force, in Newtons, acting on the cannon ball during its flight is Fɔ = -0.5v. The resulting acceleration, in m/s³, of the cannon ball due to this headwind and drag is a=-(10+0.5v, )i-(9.81+0.5v,)j where the components of velocity are in m/s. Determine the time of flight of the cannon ball.
