Problem 4: throwing an apple straight up with drag for reference see events finding and odes pdf document on assignment drag force is a vector in the opposite direction of an objects velocity vector. which means the governing differential equations of an apple thrown straight up can be modeled with a piecewise differential. = − − cc ∗ � � 2 while the ball is apple is rising = − + cc ∗ � � 2 while the ball is apple is falling where g is the acceleration due to gravity (9.8 m/s2 ) and c is the drag coefficient. use odeset, "events" with ode45 to find how long an apple will be in the air if: • it is thrown straight up from an initial height of 2.5 m • it has an initial velocity of 10 m/s • c = 0.1
