Modify the code so that the following are displayed in the animation display window: 1. Projectile mass. 2. Launch angle 3. Launch speed 4. Current speed. 5. Maximum height. 6. Horizontal distance traveled 7. Comment out or replace the drag force with the air resistance of the form 7a air resistance COAV²0 Here, C is the drag coefficient, pis air density, and A is the frontal area of the projectile. In this lab, we will choose C=0.1, p= 1.225 kg/m³ and the frontal area is the area of a circle with the same radius as the sphere.
